Amides and amines do not form esters: amides are the most stable of the carboxylic acid derivatives and so don’t undergo the reaction; and amines are nucleophiles, just like alcohols, so they won't react together

Acid chlorides are the least stable of the carboxylic acid derivatives so they will happily react to form esters, and you obviously know that carboxylic acids will too; this therefore leaves only 3 and 4, and so the answer is C

oh so we dont necessarily need carboxylic acid reacting with alcohol. we can just use a derivative?

As an aside, are acyl chlorides more unstable than their equivalent acid anhydrides?

They are more reactive, as the condensation product is the volatile HCl rather than the acid produced from the anhydride.

Yes, this is correct: charco already explained why this is the case

The acid chlorides are categorically the most reactive of the derivatives, and the acid anhydrides come after them in the derivative ‘reactivity series’ (whatever you want to call it)

That is correct; the derivatives have to be acid chlorides or acid anhydrides though
