What is the correct call?

[Marty Rogers]

When a thrower-in causes the ball to go directly to the basket support (hitting or lodging), or causes the ball to be lodged in the flange, they are both violations. Other violations are: leaving the designated spot, pass ball to a teammate out-of-bounds (spot throw-in), consume 5 seconds, carry ball onto court, first to touch ball on court, throw ball directly in basket, hand ball directly to teammate. In all cases, they are not AP situations (not like a held ball), so the AP arrow doesn't change. Other team gets ball at that spot of violation, AP arrow stays the same.
Rule 9 Section 2
The only exception to this is when the ORIGINAL throw-in is an AP throw-in. In that case, if the thrower-in violates, he loses the ball AND the possession arrow. For example, A1 throws the ball in (on his AP throw in), but steps over the line as he releases the ball. Referee tweets, stops clock, gives ball to B, and the arrow is also pointed to B (when throw-in is completed). Not to be confused with the jump ball violation to start the game, where the violating team gets the arrow.

So, the answer to the original question would have been FALSE, even if the ball had been lodged in the flange.
One other thought; if you are reviewing old tests, some of the answers may be wrong because of rules changes since they were published. Be sure you have the updated answers.
Good Luck
