Dedendum greater then addendum is the Right answer.
Dedendum= addendum + clearance so dedendum always greater then addendum.
Dedendum= addendum + clearance so dedendum always greater then addendum.

Addendum > Dedendum.
Pitch circle = [(πD)/T] .
D= Pitch cycle dia, T= Number of teeth.
Dedendum dia is a base circle dia .
so, Base circle < Pitch circle is always.
That's why a correct answer is an option [C].

Addendum- it is the radial height of a tooth above the pitch circle.its standard value is one module.
Dedendum- it is the radial depth of a tooth below the pitch circle. It's standard value is 1.157m.

Clearance = Dedendum - Addendum.
= 1.157 module - module.
= 1.157 module - module.

@All.
It is written pitch circle diameter =module * a number of teeth.
As we know that;
Module=pitch circle dia/no.of teeth.
So, option B is also correct.

The formula of module is diameter/no of teeth.
Hence option B.
Hence option B.

Addendum is 1m.
Dedendum is addendum+clearance =1m + 0.157m=1.157m.
i.e 0.157 larger than addendum.
Dedendum is addendum+clearance =1m + 0.157m=1.157m.
i.e 0.157 larger than addendum.
