MCQ (Single Correct Answer)

Consider the following two threads T1 and T2 that update two shared variables a and b. Assume that initially $a = 1$ and $b = 1$. Though context switching between threads can happen at any time, each statement of T1 or T2 is executed atomically without interruption.

T1:
$a = a + 1$;
$b = b + 1$;

T2:
$b = 2 * b$;
$a = 2 * a$;

Which one of the following options lists all the possible combinations of values of a and b after both T1 and T2 finish execution?

$(a = 4, b = 4); (a = 3, b = 3); (a = 4, b = 3)$

$(a = 3, b = 4); (a = 4, b = 3); (a = 3, b = 3)$

$(a = 4, b = 4); (a = 4, b = 3); (a = 3, b = 4)$

$(a = 2, b = 2); (a = 2, b = 3); (a = 3, b = 4)$
