Determine the correctness or otherwise of the following Assertion (a) and the Reason (r): Assertion: Somatic embryogenesis in plants is a two-step process comprising of embryo initiation followed by embryo production. Reason: Embryo initiation is independent of the presence of 2,4-dichlorophenoxyacetic acid whereas embryo production requires a high concentration of 2,4-dichlorophenoxyacetic acid. (A) both (a) and (r) are true and (r) is the correct reason for (a) (B) both (a) and (r) are true and (r) is not the correct reason for (a) (C) (a) is true but (r) is false (D) (a) is false but (r) is true

An immobilized enzyme being used in a continuous plug flow reactor exhibits an effectiveness factor (η) of 1.2. The value of η being greater than 1 could be apparently due to (A) substrate inhibited kinetics with external pore diffusion limitation (B) internal pore diffusion limitation (C) sigmoidal kinetics (D) unstability of the enzyme
