Correct Answer:

Solution : According to the given figure series –
From Box 1 to Box 2 – The square becomes unshaded and shifts at the first position followed by the unshaded triangle at the second position and the circle at the third position. The symbol at the third position, i.e., the circle becomes shaded. The letter A is being increased by three, resulting in the letter D.
From Box 2 to Box 3 – The circle becomes unshaded and shifts at the first position followed by the unshaded square at the second position and the triangle at the third position. The symbol at the third position, i.e., the triangle becomes shaded. The letter D is being increased by three, resulting in the letter G.
From Box 3 to Box 4 – The triangle becomes unshaded and shifts at the first position followed by the unshaded circle at the second position and the square at the third position. The symbol at the third position, i.e., the square becomes shaded. The letter G is being increased by three, resulting in the letter J.
Similarly, from Box 4 to Box 5 – The square will become unshaded and will shift at the first position followed by the unshaded triangle at the second position and the circle at the third position. The symbol at the third position, i.e., the circle becomes shaded. The letter J will be increased by three, resulting in the letter M.

The following figure will complete the given pattern –

Hence, the fourth option is correct.
