Answer 1

Right option is (b) Pollens of a flower falling on the stigma of the same flower

To explain I would say: Self-pollination means fertilization by pollens of the same flower. When the pollens from the anther fall on the stigma of the same flower, the style carries the pollen to the ovaries. This is known as self-pollination.
