Answer: (A)

d b f a c e

The order of steps followed in the formation of cement is :

(i) Mixing of raw materials $\left(d\right)$
(ii) Crushing $\left(b\right)$
(iii) Calcination in a rotary kiln $\left(f\right)$
(iv) Clinker formation $\left(a\right)$
(v) Addition Gypsum $\left(c\right)$
(vi) Grinding to line powder $\left(e\right)$

Hence, the correct option is $\left(A\right)$.
