Solution:

The total number of cats up for adoption is


=16

The number of male cats is


=7

The number of female cats is


=9

Since 5 cats are to be picked and he prefers only female cats, the probability will be


\begin{gathered} =(9)/(16)*(8)/(15)*(7)/(14)*(6)/(13)*(5)/(12) \\ =(3)/(104) \\ \end{gathered}

Hence,

The final answer is


\Rightarrow(3)/(104)

The SECOND OPTION is the right answer
