I am afraid he is burning the candle at both ends and ruining his life. A. wasting his money B. becoming overgenerous C. overtaxing his energies D. losing his objectives

The correct answer is C. overtaxing his energies.

The phrase “burning the candle at both ends” means to work too hard and not get enough rest. This can lead to health problems, such as fatigue, stress, and anxiety. It can also lead to problems in other areas of life, such as relationships, work, and school.

Option A is incorrect because wasting money is not the same as overtaxing one’s energies. Option B is incorrect because becoming overgenerous is not the same as overtaxing one’s energies. Option D is incorrect because losing one’s objectives is not the same as overtaxing one’s energies.
