Answer:
Option (A) , (b) and (d) are correct option 
Explanation:
According to Coulomb's law electric force between two charges is given by 

From the relation we can say that force is directly proportional to magnitude of charges and inversely proportional to distance between them '
So if we increase the distance then force will decrease 
Increase if any of the charge get larger
If force is attractive then both the charge will be of different sign and is force is repulsive then both the charges of same sign 
From above conclusion we can say that (a), (b) and (d) are correct option
