Answer 1

Right option is (c) Mutation

To explain: Mutations in the bacterial strains increases the yield of alpha-amylase. The single mutation increases the yield to a greater extent. If the mutation is increased from 2 to 7 times then, the yield of amylase increases 250 times greater than the wild bacterial strain.
