d. none of these

The sentence that has a misplaced modifier is A.

Explanation:

The sentence that has a misplaced modifier is A. A misplaced modifier is a word, phrase, or clause that is separated from the word it modifies or describes. Because of this separation, sentences with this mistake often sound awkward.

In A, the misplaced modifier is the participle phrase "wearing shorts and sneakers".  The position of said modifier makes the sentence sound as if the one wearing shorts and sneakers was the dog. The modifier should be placed next to the noun it is supposed to modify. Therefore, a possible version of the sentence would be the following: Wearing shorts and sneakers, I walked my dog this morning.
