A "rational" number has nothing to do with sensibility.  It means a number that can be expressed as a ratio.

 

Regarding A and B, since I can see at a glance the answer is D I'm not going to waste my time with them.

 

The square root of 3 cannot be expressed as a ratio, so multiplying it by 0.5 won't change that. 

 

Assuming only one answer is correct, that answer is D.  1/3 x 0.5 = 0.5/3 = 1/6
