The correct option is B Destiny
Let's examine the sentence: "Man is the maker of his own ________." The sentence says that man or a person makes his own something. This something is to be filled in the blank and the two choices given are Destiny and Destination. The noun 'destiny' means a person's fate while the noun 'destination' means the end point of a journey. It's clear that no one can make the end point of his or her journey as it already exists. However, one can make one's fate or fortune by one's decisions and actions as one's destiny does not exist already. Hence, going by the meaning of the nouns, 'destiny' is the right choice for the blank in the sentence. So, Option B is the correct answer.
