Fischer esterification is which type of reaction:

Explanation

A carboxylic acid and an alcohol join with the loss of a small molecule, water, which is the definition of a condensation, and concentrated sulphuric acid catalyses it while also shifting the equilibrium by removing that water. The reaction is reversible, so the yield is never complete. Nucleophilic acyl substitution describes the mechanism, but the reaction type the question asks for is condensation.
