Assertion: In angiosperms, the male gamete consists of three cells.
Reason: The male gametophyte contains two sperm cells and a vegetative cell that gives rise to the pollen tube.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion and reason are false.
The assertion is false, as the male gamete in angiosperms consists of two cells, not three. The reason is true, as the male gametophyte contains two sperm cells and a vegetative cell that gives rise to the pollen tube. However, the reason cannot be the correct explanation of the assertion, since the assertion itself is false.
Option 4 is the correct answer.
