The correct option is B Fallopian tube
Fertilization (in humans) is the union of human egg (female gamete) and sperm (male gamete). It occurs in the fallopian tube or oviduct. After ovulation, the ovum comes out of the ovary and it is received by the fallopian tube, where the sperm comes and fertilise the ovum during fertilisation.
So, the correct answer is option B.
