Pick up the incorrect statement from the following. In case of suspension bridge due to rise in temperature, A. Dip of the cable increases B. Length of the cable increases C. Dip of the cable decreases D. None of these

The correct answer is: C. Dip of the cable decreases.

When the temperature of a suspension bridge increases, the steel cables that support the bridge expand. This expansion causes the cables to sag more, which increases the dip of the bridge.

The length of the cable also increases, but this is not the main cause of the increase in the dip of the bridge. The main cause is the expansion of the cable.

The following is a brief explanation of each option:

• A. Dip of the cable increases. This is the correct answer.
• B. Length of the cable increases. This is true, but it is not the main cause of the increase in the dip of the bridge. The main cause is the expansion of the cable.
• C. Dip of the cable decreases. This is incorrect. The dip of the cable increases when the temperature of the bridge increases.
• D. None of these. This is incorrect. Option A is the correct answer.
