Explanation

Option A is correct because microbial fermentation reactions are typical autocatalytic reactions. Option B is true since the slowest step limits the rate in irreversible series reactions. Option C holds because fractional conversion is the same for constant and variable volume systems in irreversible first-order reactions. However, option D is incorrect because ester hydrolysis in acidic or alkaline media follows first-order kinetics, not zero-order.
