My cousin lives . . . . . . . . my house. A. on B. over C. across D. in front

The correct answer is: D. in front

The other options are:

• A. on – This means that your cousin lives on top of your house. This is not a likely scenario.
• B. over – This means that your cousin lives above your house. This could mean that they live in an apartment building above your house, or that they live in a house that is on a hill and your house is at the bottom of the hill.
• C. across – This means that your cousin lives on the other side of the street from your house. This is a likely scenario.

I hope this helps!
