D.\$85, \$25, \$20
E.\$25, \$60, \$70

Since Samantha owns equal amounts of stocks, the 10% increase alone should set off the 15% decrease in each of the other two stocks. i.e The stock which increased should have a substantially higher value than the two stocks which decreased. Between B & D, D is obviously the safer bet and is the right answer.

Kudos Please... If my post helped.
