D. close
Feedback Some adverbs have the same form as adjectives: e.g. fast (not fastly), left, hard, outside, right, straight, late, well. And in the test sentence we meet one of such adverbs: the adverb ‘close’ is the adverb of place (She hates people standing (where?) too close to her.). This adverb collocates with the preposition ‘to’: Sheila was standing dangerously (where?) close to the edge of the cliff.; The girl clutched her bag (where?) close to her chest.; They stood (where?) close to the door. And in the test sentence we are given this preposition: ‘…to me.’. Though ‘closely’ can be used in the meaning of ‘carefully’.
