Ava's machine takes four-digit positive integers as input. When the four-digit integer $A B C D$ is input, the machine outputs the integer $A \times B+C \times D$. For example, when the input is 1234 , the output is $1 \times 2+3 \times 4=2+12=14$. When the input is 2023 , the output is
(A) 0
(B) 2
(C) 3
(D) 6
(E) 8
Using the given rule, the output of the machine is $2 \times 0+2 \times 3=0+6=6$.

ANSWER: (D)
