Explanation:
This question is testing the understanding of modals in English grammar. Modals are auxiliary verbs that express various degrees of necessity, possibility, permission, or ability. In this case, we need to determine which modal verb best fits the sentence.

Options:
a) Can - This modal verb indicates the ability or possibility to do something. It does not convey a strong sense of certainty or prediction. Therefore, it is not the correct answer in this context.

b) May - This modal verb is used to express permission or possibility. It does not convey a strong sense of certainty or prediction. Therefore, it is not the correct answer in this context.

c) Will - This modal verb is used to express future certainty or prediction. It indicates that something is expected or likely to happen. In this sentence, "will" suggests that the person will definitely like the dress based on her style. Therefore, "will" is the correct answer.

d) Must - This modal verb is used to express strong obligation or necessity. It implies that something is required or necessary to happen. However, in this sentence, we are not discussing a requirement or necessity. Therefore, it is not the correct answer in this context.

e) None of these - This option indicates that none of the given modal verbs are suitable for the sentence. However, as explained above, the correct answer is "will."

Conclusion:
In conclusion, the correct answer is option 'C' - "will" because it expresses future certainty or prediction, suggesting that the person will definitely like the dress based on her style.
