Answer: b. ii and iii

Explanation:

The ester, Butyl Butanoate is formed when Butanol reacts with Butanoic acid

as seen below;

CH3-CH2-CH2-CH2-OH  +  CH3-CH2-CH2-COOH     ---->

Butanol                                     Butanoic acid

CH3-CH2-CH2-COOCH2-CH2-CH2-CH3   +          H2O

Butyl Butanoate                                                      Water
