Find the digits A and B in the multiplication problem?

In the multiplication problem at the right, A and B stand for different digits. Find A and B.

B × A should have digit 4 in units place and A×A should be less than 11

as AB×A = 114 

The options are 

B=4 & A=1

B=2 & A=2

B=8 & A=3

From the options only feasible solution is A=3 and B=8

So in the given multiplication problem A=3 and B=8
