Stand ____ where I can see you.

Solution:

The word here is best suitable for the given sentence.
An adverb is a word or phrase that qualifies or modifies an adjective, verb, or another adverb to communicate a situational, causal, or other relationship. The right answer is 3 in this case since it identifies the location of the speaker (where I can see you). Options 1, 2, and 4 are incorrect since 'everywhere' means everyplace, 'up' means above something, and 'backward' means behind something else. Stand here where I can see you.
