First, convert the numbers into binary form.

x = 10 = 1010
y = 6  = 0110

The bitwise AND gives:

x & y = 0010 = 2

Right shift by $\texttt{1}$ divides by $\texttt{2}$ using integer movement of bits.

x >> 1 = 10 >> 1 = 5

Left shift by $\texttt{1}$ multiplies by $\texttt{2}$ using bit movement.

y << 1 = 6 << 1 = 12

In Python, $\texttt{~n}$ is equal to $\texttt{-(n + 1)}$.

~1 = -2

Therefore:

result = 2 + 5 + 12 - 2 = 17

Correct Option: A
