True or false: a single affine cipher constructed as a composition

True or false: a single affine cipher constructed as a composition of two affine ciphers is guaranteed to always have this property. Justify your answer with one of the explanations below. False, because multiplication by a mod N is not always reversible. True, because the two multiplicative terms both selected from ZX are guaranteed to produce a product also in ZN for the combined affine cipher. True, because the resulting affine cipher is a one-to-one function on ZN. False, because the resulting affine cipher is not a one-to-one function on Zn
