Topic: Preposition, Subject: English Grammar (ইংরেজি গ্রামার)

Best Answer Explained in Below-:

In the sentence "A dove flew ____ my head," the blank requires a preposition that accurately describes the positional relationship between the dove and the speaker's head. The correct option is "over."

The preposition "over" indicates a position that is higher than something else. When we say a dove flew "over" someone's head, it implies that the dove is flying in a path that is above the person, without making contact. This conveys a sense of movement in relation to the speaker's position and creates a visual image of the dove soaring above them.

The other options do not fit this context correctly. "In" would suggest that the dove is inside or among something, which doesn’t make sense here, as a bird cannot naturally be "in" a person's head. "On" would indicate a physical contact or resting position on the head, which is not applicable in this instance. Lastly, "the" is not a preposition but an article, which cannot correctly fill in the blank.

Thus, "over" is the most appropriate choice as it accurately describes the dove's flight in relation to the person's head.
