The answer is C.

while (false){}, for example, is a statement that does not require a semicolon.

You can even write an entire program in C without a semicolon:

#include <iostream>
int main()
{
    if (std::cout << "Hello World"){
    }
    // returning zero is implicit in main
}

Although really, knowing this is not going to make you a better C programmer. Contributing to open source projects or getting a job in the field would.

The answer is C.

The grammar production for a for statement is

for ( init-statement condition_opt ; expression_opt ) statement

So, in

for (int i = 0; i < 10;   i)

the first ; ends the "init-statement". The second ; is part of the for loop grammar, and does not end a statement.
