Answer:
The correct answer is option A. "Line spectra".
Explanation:
Line spectra is a method that is used to determine the temperature of a star. Line spectra is based on the principle that, depending on the temperature of a star, a line is traced which is compared to the continuum temperature that could either generate a emission (hotter) or absorption (colder) line. A spectrum of lines depending on the temperature have been established under the code OBAFGKM, where O is the hottest an M is coldest.

For example, insects use wings to fly like bats and birds, but the wing structure and embryonic origin is completely different. These are called analogous structures... Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous.

The organs that are involved in the excretion of water from the body include:
1. Kidneys (Primary organ for water removal)
2. Skin
3. Lungs
The kidneys play a key role in maintaining the water balance of the body. The kidneys control the water levels in the body by conserve water when there is shortage, and they can expel excess water by diluting the urine.
The skin has water in it. This water gets lost to the atmosphere by the process of evaporation. This is independent of the process of sweating wherein the skin actively releases water in the form of sweat to cool the body.
Our breath has a lot of moisture in it. This moisture is present due to the evaporation process taking place within the lungs due to the heat of the body. Thus lungs also become a part of the water loss mechanism.
