2024 AMC 10B Problem 16

Jerry likes to play with numbers. One day, he wrote all the integers from 1 to 2024 on the whiteboard. Then he repeatedly chose four numbers on the whiteboard, erased them, and replaced them by either their sum or their product. (For example, Jerry’s first step might have been to erase 1, 2, 3, and 5, and then write either 11, their sum, or 30, their product, on the whiteboard.) After repeatedly performing this operation, Jerry noticed that all the remaining numbers on the whiteboard were odd. What is the maximum possible number of integers on the whiteboard at that time?

\textbf{(A)} 1010 \qquad \textbf{(B)} 1011 \qquad \textbf{(C)} 1012 \qquad \textbf{(D)} 1013 \qquad \textbf{(E)} 1014
