(B) Statement $(1)$ is True: The fusion of a male gamete (sperm) and a female gamete (ovum) is defined as fertilization.Statement $(2)$ is True: $A$ rapid secretion of Luteinizing Hormone $(LH)$ during the mid-cycle,known as the $LH$ surge,induces the rupture of the Graafian follicle and thereby leads to ovulation.Statement $(3)$ is False: The embryo with $8$ to $16$ blastomeres is called a morula. An $8$-celled stage is typically referred to as an early morula,but the term 'morula' is specifically applied to the $8-16$ cell stage.Statement $(4)$ is True: The fallopian tube (oviduct) in humans is approximately $10-12 \, cm$ long,but $8-10 \, cm$ is often cited in various standard textbooks as the approximate length range.Therefore,all statements are considered correct in the context of standard biological curriculum.
