The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.

Answer:
A
Explanation:
Answer is A because, production of gametes happens in meiosis. So, the first splitting of one cell into two daughter cell occurs in telophase I and then in each of these daughter cells in meiosis II  those sister chromatids separate into full fledged chromosome and each daughter cell splits into two different cells. So at end you have 4 new non-identical daughter cells.
