To find the new position of the submarine after it ascends 200 feet from its original position of 650 feet below sea level, we can represent the depth below sea level as a negative number.
Initially, the submarine's depth is -650 feet (since it's below sea level). If it ascends 200 feet, we can calculate its new position as follows:
\[
-650 + 200 = -450
\]
Thus, the new position of the submarine is -450 feet.
The correct answer is **C. -450**.
