Full Explanation
Effective prompts balance completeness against conciseness. Too short: missing context leads to wrong assumptions. Too long: irrelevant padding can bury key instructions ('lost in the middle' problem), increases cost, and slows responses. The ideal prompt includes all genuinely relevant context, constraints, and examples while omitting redundant or tangential information. Option A is wrong — there's diminishing returns and 'lost in the middle' effects. Option C is wrong — overly brief prompts often lead to poor results due to insufficient context. Option D is wrong — prompt length directly affects both cost (input tokens) and quality.
