"interact with" is idiomatically correct; anything else is unidiomatic; eliminate B, D, and E.

Choice A makes the same error; it ends with "between", while the correct idiom demands "with" (i.e., we need "interact...with" not "interact...between"); eliminate A.

All four wrong answers use the wrong idiom; choice C is the only one that uses "interact with" both times.
