First, we need to determine the price per contact in each of the two choices.

We begin by performing 50/25= <<50/25=2>>2 contacts per every dollar spent on choice A.

Next, we determine the price per contact of the alternate choice.

We do this by performing 99/33= <<99/33=3>>3 contacts for every dollar spent on choice B.

Since 3>2, Adrian purchases choice B.

The answer is therefore 3.
