Option 1 states that cold fronts move at a slower rate than warm fronts and therefore cannot overtake the warm fronts. This means that warm fronts are able to move faster and overtake cold fronts.

Option 2, on the other hand, suggests that cold fronts normally move faster than warm fronts and frequently overtake them. This contradicts the correct answer.

Option 3 reiterates that cold fronts move at a slower rate but eventually they are overtaken by warm fronts. This aligns with the correct answer, as it acknowledges that warm fronts can overtake cold fronts.

Option 4 states that cold fronts move faster than warm fronts but they cannot overtake them. This contradicts the correct answer, which states that warm fronts are not overtaken by cold fronts.

Therefore, the correct answer is option 1, as it correctly states that cold fronts move at a slower rate than warm fronts and cannot overtake them.
