Which of the following chemical transformations is incorrectly depicted?

Step-by-step solution

Option (A): NaBH ₄ is a mild reducing agent. It can reduce aldehydes, ketones, and acid chlorides, but it is not strong enough to reduce carboxylic acids, esters, or amides. Therefore, the reduction of cyclohex-3-ene-1-carboxylic acid to cyclohex-3-en-1-ylmethanol using NaBH ₄ will not take place. This transformation is incorrectly depicted. Option (B): LiAlH ₄ is a strong reducing agent that successfully reduces carboxylic acids to primary alcohols without affecting isolated carbon-carbon double bonds. This transf
