B.41 since the side you’re looking for is the hypotenuse it is the longest side. Therefore, the only answer that is longer than 40 is 41
The answer of how it is convert is the sun generates energy
by slowly contracting in size; converting gravitational potential energy into
thermal energy and this is called gravitational contraction. Gravitational collapse is the narrowing of an
astronomical object due to the effect of its own gravity, which tends to draw
matter inward toward the center of gravity.
The state of the object on which the net force is zero is 'constant uniform motion',
or 'unaccelerated motion'.
Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
