I=8, the condition I > 100 is not satisfied, and the execution loop body, s = 2+14+16+18,

I= 10, if the condition I > 100 is not met, the loop is executed, and S = 2+14+16+18+10.

…

The rest can be inferred.

I=98, the condition I > 100 is not satisfied, and the execution loop is s = 2+14+16+…+198.

I= 100, if the condition I > 100 is not met, the loop is executed, and S = 2+14+16+…+1100.

I= 102, if the condition I < 100 is met, the loop is exited.

Output s = 2+14+16+…+1100,

So choose C.
