The correct path for pollen as it fertilizes a plant is:
anther - stigma - style - ovary
However, since that option isn't listed, the closest correct option from the ones provided is:
anther - style - stigma - ovary (which actually contains an incorrect order for fertilization).
The correct order is that pollen is released from the anther, lands on the stigma, travels down the style, and then fertilizes the ovule in the ovary. Please note the crucial step of the stigma preceding the style in the pollen transfer process.
