愛着 (あいちゃく) means 'attachment, fondness, affection' toward a person or thing. 愛着がある ('to feel attached to') is the standard collocation. The speaker has used the table since childhood and feels sentimental attachment, so they can't bring themselves to throw it away.

• 1心情 (しんじょう) means 'state of mind, feelings, mood' (e.g., 複雑な心情 'complex feelings'). It describes one's inner emotional state generally, not attachment to a specific object, and does not naturally collocate with がある in this way.
• 2好感 (こうかん) means 'favorable impression' (e.g., 好感を持つ 'have a favorable impression'). It is used toward people or their actions, not toward a long-used personal possession.
• 3熱意 (ねつい) means 'enthusiasm, zeal, passion' (e.g., 熱意を込める 'put enthusiasm into'). It describes energetic dedication to a goal or activity, not sentimental attachment to an object.

• 愛着あいちゃく — attachment, fondness, affection (toward something)
• 心情しんじょう — state of mind, feelings, mood
• 好感こうかん — favorable impression
• 熱意ねつい — enthusiasm, zeal, passion

Option 4 (ノウハウ) is correct. ノウハウ (know-how) refers to practical knowledge, techniques, or expertise gained through experience. The phrase 経営のノウハウを学んだ (learned the know-how of management) is a natural and common collocation, meaning the current company president learned practical management skills/techniques from the founder.

• 1データベース (database) refers to a structured set of data held in a computer. You cannot 'learn' a database in the sense of acquiring management skills, so 経営のデータベースを学んだ does not make sense.
• 2ベテラン (veteran) refers to an experienced person or veteran. It is a noun describing a person, not knowledge or skills to be learned. 経営のベテランを学んだ is grammatically and semantically unnatural.
• 3ライフワーク (life work / lifework) refers to one's life's work or a long-term personal project. While a founder might consider management their lifework, you do not 'learn' someone's lifework as a transferable skill. 経営のライフワークを学んだ is not a natural expression.

• ノウハウ — know-how; practical knowledge or technique (especially in business)
• データベース — database
• ベテラン — veteran; experienced person
• ライフワーク — life work; lifework; one's long-term personal project or mission
• 経営けいえい — management; administration; running a business
• 創立者そうりつしゃ — founder (of an organization/company)

「安堵した（あんどした）」means 'felt relieved.' Option 3「ほっとした」also means 'felt relieved,' making it the closest paraphrase: 'I felt relieved by that one remark.'

• 1「すっとした」means 'felt refreshed / felt clear-headed,' describing a sense of lightness or clarity, not relief from anxiety.
• 2「はっとした」means 'was startled / was suddenly surprised,' the opposite nuance of relief.
• 4「かっとした」means 'got angry / flared up,' unrelated to feeling relieved.

• 安堵あんど — relief; feeling of reassurance (安堵する = to feel relieved)
• ほっとする — to feel relieved; to breathe a sigh of relief
