This is wrong because addendum circle is always greater than dedendum circle.

Dedendum = 1.157*addendum.
Addendum = radial distance from pitch circle to top of tooth.
Dedendum = radial distance from pitch circle to base of the tooth.
Addendum = radial distance from pitch circle to top of tooth.
Dedendum = radial distance from pitch circle to base of the tooth.

Module m: Pitch diameter divided by number of teeth: m= D/T.
Circular pitch p: The width of a tooth and a space, measured on the pitch circle. Cp= π*D/T.
Diametral pitch P: The number of teeth of a gear per inch of its pitch diameter. Dp = T/D.

Pitch circle diameter is the product of module and not no of teeth.

Please, is it must for the pitch circle diameter to be greater than the base circle diameter.

Please, give an explanation about option B.

Addendum is the distance from pitch circle to the teeth head, so it must be less than dedendum.
