As we learnt in concept

Composition of equilibrium mixture when Kc > 1000 -

If Kc > 103,  products predominate over reactants i.e. if Kc is very large, the reaction proceeds nearly to completion.

- wherein

e.g. 

H_{2}+ Cl_{2}\rightleftharpoons 2HCl
 

K_{c}=4\times 10^{31}

 

H_{2}+Br_{2}\rightleftharpoons 2HBr
 

K_{c}=5.4\times 10^{18}

 

 The valve of K is very high means reaction proceeds almost to completion i.e. the system will contain mostly products.

mostly reactants 

This option is incorrect.

Option 2)

mostly products 

This option is correct.

Option 3)

similar amounts of reactants and products 

This option is incorrect.

Option 4)
