Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): Direct somatic embryogenesis is generally rarer than indirect somatic embryogenesis.

Reason (R): Direct embryogenesis occurs from "Pre-Embryonic Determined Cells" (PEDCs) which are found only in specific embryonic tissues like the scutellum or nucellus.
