Correct option is B
in double fertilization after entering one of the synergids, the Pollen tube releases the two male gametes into the cytoplasm of the synergid. Fusion of male gamete and egg produces a zygote and this is called syngamy, fusion of a male gamete and two fused polar nuclei produces primary endosperm nucleus (PEN) this is called triple fusion. Non-albuminous seeds have no residual endosperm as it is completely consumed during embryo development (e.g., pea, groundnut). Albuminous seeds retain a part of endosperm as it is not completely used up during embryo development (e.g., wheat, maize, barley, castor).
