The following sequence of operations is executed:

Pop -

Push 3 -

Push 4 -

Push 6 -

Push 7 -

Pop -

Pop -

Pop -
What is the value of the top element after these operations are executed?

Answer options

Correct answer: B

Explanation

After executing the operations, the sequence of stack manipulations results in the final top element being 3. The initial pushes add values to the stack, and the pops remove values in a Last In First Out (LIFO) manner, leading to 3 being the last value pushed before the final pop operations.
