Order of a Reaction -
The order of a reaction is determined as the sum of the powers of the concentration terms that appear in the experimental rate equation. It is an experimental quantity.

 

Rate = k[A][B]^{1/2}

Order = 1+\frac{1}{2}= \frac{3}{2}

It can be zero/fraction/negative/positive fractional.

Order = 3/2 =1.5

Therefore, option(3) is correct
