Solar eclipse occurs when

A solar eclipse occurs when the Moon passes directly between the Sun and Earth, which corresponds to option [A]. This alignment results in the Moon casting a shadow on Earth’s surface, blocking all or part of the Sun’s light. From Earth’s perspective, the Sun appears to be obscured either partially (partial solar eclipse) or completely (total solar eclipse) by the Moon. This phenomenon happens when the Moon, in its orbit around Earth, reaches a point where it crosses the plane of Earth’s orbit around the Sun (the ecliptic plane) and aligns directly between Earth and the Sun. Solar eclipses are observable from specific regions on Earth’s surface where the Moon’s shadow falls, creating a unique spectacle of celestial alignment and temporary darkness during the day. Understanding the precise alignment of Sun, Moon, and Earth is essential for predicting and observing solar eclipses accurately.
