Explanation:
In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.
The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.
The other options are not correct because the pollen tube:

</em>
- <u><em>Does not lead the eggs to the male spermatophytes</em></u><em>.</em>
