This code uses two separate cout statements with a space between the two words in the second statement, resulting in a single line containing "hello there". Option A would also work, but it splits "hello" and "there" over two separate cout statements, which is less efficient. Option B uses a comma instead of the insertion operator, which is not valid syntax for cout. Option C prints "hellothere" with no space between the two words.
