Dead Ball or Count the Basket

[williebfree]

Directly under Team A's basket, A1 is fouled by B1 (contact on the arm) while attempting an underhand scoop shot. During continuation of the try, the ball traveled through the basket from the bottom, hit the backboard and then fell back through the hoop.

What is the correct ruling?
A. Foul, try is successful, award two points and a free throw.
B. Foul, try became dead when it enters basket from below, award two free throws.

Rule 5-1 does not specifically address a ball traveling through the basket from below prior to entering it from above.

Rule 6-7 does not specifically address situation, other than to confirm "with continuation" the ball does not become dead until the try ends.
