Answer:
The correct answer would be 37.
Egg or sperm or gametes are cells produced by the process of meiosis and carry half the number of chromosome (n) present in a parental cell (2n).
Meiosis is a type of cell division which results in the formation of four daughter cells each having exactly half the number of chromosome present in parent cell.
The sperm unite or fertilize with egg which restore the chromosome number (2n) in the zygote.
