When do you start the shot clock?

a) when the throw-in pass is tipped by A2
b) when the throw-in pass is tipped by B1

From the current NCAA rules:
Rule 2
Section 11. Duties of Shot-Clock Operator
The shot-clock operator shall:...

5. Start the timing device when a player inbounds legally touches or is
touched by the ball on a throw-in or when a team initially gains possession
from a jump ball, an unsuccessful try for goal or when possession is gained
of a loose ball after a jump ball or unsuccessful try for goal.
