Provide one reason that preventing fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time

To produce a healthy offspring.

Explanation:

To make a healthy offspring is the reason that is responsible for preventing fusion of multiple sperm with one egg in sea urchins because if more sperm are fused with one egg, faulty segregation of chromosomes occurs during cell division that leads to the production of nondiploid cells due to which no further development occurs. So by avoiding such type of faults in the cell, only one sperm will fuse with egg not multiple sperms.
