The correct answer is D. bear.
The other options are not correct because:
- Appreciate means to recognize the value of something.
- Digest means to process food or information.
- Accept means to agree to something or to receive something willingly.
In the sentence, "Power went to her head and she could not stand even minor criticism," the woman is being described as being arrogant and intolerant of criticism. This suggests that she is unable to bear even the slightest criticism, let alone appreciate, digest, or accept it.
