I found the exercise on the internet and bellow are the options:
"A. Seed cones contain ovules. 
B. Germinated seeds are haploid. 
C. A pollen tube is used to prevent the fertilization process. 
<span>D. Pollen grains undergo meiosis to form egg cells."

The correct answer is D.
There are no seed cones, but pollen cones, where the ovules can be found. Germinated seeds are diploid, not haploid. The pollen tube role is to promote the fertilization process by leading the sperm to the egg, once the sperm in this type of plants do not have flagella and therefore no movement.
The correct answer is D because pollen grains are really the diploid germinative cells that </span><span>produce sperm cells.</span>
