The elements of the problem figures given below are changing with a certain rule as we observe them from left to right:

Correct Option (D)

The given problem figures follow a specific logical sequence based on two distinct rules:

• The position of the triangle shifts in an anti-clockwise direction across the four corners of the square frame.
• The orientation of the triangle (pointing upwards or downwards) alternates with each successive figure.

Analyzing the sequence:

1. Figure 1: Triangle is in the top-left corner, pointing upwards.
2. Figure 2: Triangle moves to the top-right corner, pointing downwards.
3. Figure 3: Triangle moves to the bottom-right corner, pointing upwards.
4. Figure 4: Triangle moves to the bottom-left corner, pointing downwards.

Following this established pattern, for the next figure in the sequence:

• The triangle's position will move anti-clockwise from the bottom-left corner to the top-left corner.
• Since the triangle in Figure 4 is pointing downwards, the triangle in the next figure must point upwards.

Therefore, the correct figure should display a triangle in the top-left corner, oriented to point upwards. Option D accurately represents this configuration.

Incorrect Options:

• Option A: This option shows the triangle in the top-right corner, which is an incorrect position as per the anti-clockwise movement rule.
• Option B: This option shows the triangle in the bottom-left corner, which is the position of the preceding figure (Figure 4) and does not represent the next step in the sequence.
• Option C: This option shows the triangle in the bottom-right corner, which is an incorrect position. Furthermore, it depicts the triangle pointing downwards, whereas the alternating orientation rule requires it to point upwards after Figure 4.
