The correct answer is A. The statement is true. Boiling happens when the pressure in a liquid sample is equal to the pressure of its surroundings or the atmospheric pressure. For this problem, we are given the pressure of the system as 745 mmHg which is clearly not equal to the atmospheric pressure of 761 mmHg therefore boiling cannot happen.
