Option 1 states that a solar eclipse occurs when the sun is between the moon and earth. This is incorrect because a solar eclipse happens when the moon passes between the sun and the earth.

Option 2 states that a solar eclipse occurs when the earth is between the moon and sun. This is also incorrect because it is the moon that comes between the sun and the earth, not the other way around.

Option 3 states the correct answer. A solar eclipse takes place when the moon is between the sun and the earth. This happens when the moon aligns in such a way that it blocks the sun`s light from reaching the earth.

Option 4 states that a solar eclipse occurs when the moon does not lie on the line joining the sun and earth. This is not true, as a solar eclipse only occurs when the moon aligns directly between the sun and the earth.

In summary, option 3 is the correct answer.
