Sperms of both Funaria and Pteris were released together near the archegonia of Pteris. Only its sperms enter the archegonia as

Explanation

The correct answer is Pteris archegonia release chemical to attract its sperms. Archegonia are female reproductive organs in plants. They produce eggs and attract sperm cells for fertilization. Pteris archegonia release a chemical called chemoattractant to attract its sperm cells. This chemical is specific to Pteris sperm cells, so it does not attract Funaria sperm cells. Incorrect options: A. Pteris archegonia repel Funaria sperms: This is not correct. Pteris archegonia do not actively repel Funaria sperm cells. B. Funaria sperms get killed by Pteris sperms: This is also not correct. There is no evidence that Pteris sperm cells can kill Funaria sperm cells. C. Funaria sperms are less mobile: This is not necessarily true. Funaria sperm cells can be just as mobile as Pteris sperm cells.
