The 'X' symbol is moving one step and two steps anti-clockwise alternately and a new syymbol is being added once before and once after the pre-existing lines. Hence, option (c) is the correct answer.

Two and one half leaves are alternately added to the figure and the figure rotating 45° anti-clockwise. Hence, option (1) is the correct option.

The line inside the smaller circle gets outside and inside the circles alternately and also moves 45° clock wise in each step. The T outside the larger circle gets inside and outside the circles alternately, moves 45° anti-clockwise in every second step and is replaced by other symbols in every second step.The lines between the two circles move 45° anti-clockwise in each step and an extra line is added each time. Hence, option (2) is the correct answer.

All the arrows are getting inverted in each step and the position is interchanging between 1st and 2nd, 2nd and 3rd, & 3rd and 4th arrows sequentially. This process is being repeated to continue the series. Hence, option (4) is the correct answer.

In one step, the circle comes out of the square; the symbol at the centre gets replaced by a new one and the crosses outside the main figure move anti-clockwise. In the next step, the square comes out of the circle; the number of crosses increases by one and the crosses move anti-clockwise. These two steps are repeated alternately. Hence, option (2) is the correct answer.

The figure is rotating at 45° anti-clockwise in each step. In one step, the 1st and the 3rd arcs rotate at 90° anti-clockwise and in the next step all the arcs rotate at 90° anti-clockwise. The process is repeating. Hence option (4) is the correct answer.

The previous figure enlarges and a new figure is enclosed inside it while in the next step the outer figure is lost. Hence, option (4) is the correct answer.

The upper symbol is interchanging its position with the symbol in the lower left corner and the remaining two symbols interchanging positions; the symbol that reaches the lower right corner gets replaced by a new one. In the next step, the upper symbol interchanging postion with the symbol in lower right corner and the other two symbols interchange positions; the symbol that reaches the lower left corner gets replaced by a new one. The process is repeating. Hence, option (2) is the correct answer.

In each step, one of the pins is getting inverted. Hence, option (5) is the correct answer.

Three cups and one cup reverse their directions in alternate steps. Hence, option (4) is the correct answer.
