Determine the correctness or otherwise of the following Assertion (A) and Reason (R).
Assertion: In direct somatic embryogenesis, embryos are developed without going through callus formation.
Reason: This is possible due to the presence of pre embryonically determined cells.

B. (A) is false but (R) is true

C. (A) is true but (R) is false
