The F distribution is not bell-shaped, but rather right-skewed. It also depends on two degrees of freedom, one for the numerator and one for the denominator. As the degrees of freedom for the numerator and denominator both increase, the F distribution becomes increasingly symmetric. Therefore, choice C is the correct answer.
