The temperature was +21°C at 11 a.m. The temperature rose 4°C by 1 p.m. What was the temperature at 1 p.m.?

Rachel thought the answer was +25°C.

Is Rachel's answer reasonable?

A.
Yes, because the temperature started at +21°C and then got 4°C warmer, so the temperature at 1 p.m. will be warmer than +21°C.

B.
No, because the temperature started at +21°C and then got 4°C cooler, so the temperature at 1 p.m. will be cooler than +21°C.
