Step 1: The phrase “opposite to” is commonly used when referring to something directly across from something else in a physical or spatial context.
Step 2: “Opposite of” is incorrect in this context, as “opposite of” refers to something completely different in nature, not directionally across.
Step 3: “Opposed to” means to be in opposition to, which does not fit the spatial meaning intended in the sentence.
Step 4: “Opposite with” is not a standard preposition phrase.
Thus, the correct answer is: “opposite to.”
