しっかり (firmly/tightly) is correct. The sentence means 'Please close the lid tightly so the contents don't spill.' しっかりしめる (close tightly) is a natural collocation describing a firm physical action.

• 2はっきり (clearly/distinctly) — used for vision, speech, memory, etc. (はっきり見える, はっきり言う). It does not describe how tightly you close a lid.
• 3うっかり (carelessly/absent-mindedly) — describes doing something by mistake due to lack of attention (うっかり忘れる). It contradicts the intention of closing the lid carefully to prevent spilling.
• 4ぐっすり (soundly/deeply) — used exclusively for sleeping (ぐっすり眠る). It cannot modify しめる (close).

• しっかり — firmly, tightly, reliably
• はっきり — clearly, distinctly
• うっかり — carelessly, absent-mindedly
• ぐっすり — soundly (sleeping deeply)

立派な (fine, splendid, admirable) is correct: 'Mori studied hard and became a fine doctor.' 立派な modifies a noun praising its quality/status — a 立派な医者 is an admirable, respectable doctor, which fits the context of achieving a goal through hard work.

• 2盛んな (flourishing, prosperous, active) is used for events, trends, or activities (e.g., 盛んな産業 'thriving industry', 盛んな議論 'lively discussion'). It does not naturally modify a person/profession like 医者.
• 3満足な (satisfactory, adequate) describes something that meets a standard (e.g., 満足な結果 'satisfactory result'). Saying 満足な医者 sounds like 'an adequate doctor,' which is oddly lukewarm and not the intended praise.
• 4新鮮な (fresh) is used for food, vegetables, or impressions (e.g., 新鮮な野菜 'fresh vegetables', 新鮮な驚き 'fresh surprise'). It cannot describe a doctor.

• 立派りっぱな — fine; splendid; admirable; respectable
• 盛さかんな — flourishing; prosperous; active (events, trends)
• 満足まんぞくな — satisfactory; adequate
• 新鮮しんせんな — fresh (food, impressions)
