Answer 1

Option a 2 to 3 lakh

Answer 2

An ovum, the singular of ova, is a female’s gamete. A gamete is a sexual reproductive cell containing the genetic material necessary to create offspring. At birth, a female has approximately one million undeveloped ova in each of her ovaries; many of these deteriorate and are reabsorbed by the body. Unlike male sperm, however, females are unable to generate new ova. By the time a female reaches puberty (around age 12), she has only around 200,000 ova in each ovary.1 The number of ova in a female’s ovaries continues to decrease at an accelerating rate as she grows older and undergoes menstruation.
