My son is seventeen years old. He is ____ to get married ?

In the context of the sentence, the phrase "My son is seventeen years old. He is ____ to get married" requires an evaluation of whether a seventeen-year-old is generally considered appropriate or mature enough for marriage.

The correct answer is "C) too young." This option indicates that the speaker believes that at seventeen, their son is not at a suitable age for marriage based on societal norms and expectations. In many cultures, seventeen is often seen as a time for personal growth, education, and exploration rather than settling down. Therefore, saying he is "too young" conveys that he may lack the life experience, emotional maturity, or financial stability that is typically expected of individuals entering into marriage.

In contrast, "A) too old" and "B) old enough" suggest a level of age that would support marriage, while "D) enough young" is grammatically incorrect and does not convey a logical argument regarding age and marriage suitability. Thus, "too young" accurately reflects a common perception about marrying at seventeen, making it the most appropriate choice in context.
