Answer 1

The correct answer is: Option 3) i.e. signal failure.

Key Points

The original phrase "signal fall" is not a common or standard expression in English.
The term "signal failure" is widely used and understood, particularly in the context of infrastructure issues such as those caused by heavy rains disrupting signal systems.
"Signal fall" could confuse the reader as it might imply a physical falling of a signal structure, which is not typically what happens during heavy rain. Instead, the issue is a malfunction or disruption.
"Signal failure" correctly captures the idea of a disruption in the signal system due to external factors like weather conditions.

Therefore, the correct answer is: signal failure.
