Detailed Solution

Given data : It is given to identify  the function of the ZnCl2 in the given chemical reaction. 

Explanation:

ZnCl2 is a Lewis acid.
When oxygen and zinc establish a coordinate covalent connection in alcohol with a -OH group, oxygen gains a positive charge, and zinc gains a negative charge.
As a result, oxygen becomes a good leaving group, and the reaction progresses to producing the product.
An alkyl halide is created when the generated carbonium ion combines with chlorine in hydrochloric acid. Basically ZnCl2 contains here a catalyzer! 

Anti-Markonikoff's rule: The compound with the most carbon atoms will be the main product when the negative portion of the reagent is added to it.

The chemical reaction is as follows. 

C2H5OH + HCl(dry)anhydrous ZnCl2C2H5Cl + H2O

Hence, the correct option (B). to speed up the formation of C2H5Cl
