From the choices provided ... 'T' or 'F' ... the better choice is the letter ' F ', being the initial letter and therefore reminiscent of the word "False". It is the better choice in response to the statement "Forces always act alone.", because that statement is a false statement.

That simple assertion by Sir Isaac stands in sharp contradiction to the statement that begins our question above. This should be our first clue that something is awry in the statement, and that the question will lead the unwary down the primrose path if one lacks sufficient vigilance.
