Explanation:
The stellar parallax is obtained by a mathematical calculation, is a geometrical measure among the Earth and another star. For example, by now, it is known the distance from the Earth to the sun, so, is like this star can be observed by two eyes. The Earth and the Sun. If we joined the two lines from the Earth and the Sun too the star, it will form a triangle. With some calculation and the angle formed, it can be determined the distance to the star.

Answer:
Option (B)
Explanation:
The front often refers to the transition zone between the air masses that are comprised of different densities. It extends both vertically as well as horizontally. The passing of a front over a particular area depicts the change in its weather pattern. These fronts are responsible for the various weather events that cause hurricanes, tornadoes, and heavy rainfall.
There are basically 4 types of fronts, namely-
(1) Cold front
(2) Warm front
(3) Stationary front
(4) Occluded front
These front types occur when the air mass of variable densities moves from one place to another.
Thus, the correct answer is option (B).
