   As ‘S’ is a female in options (a) and (b).

   
   

   Correct Option: D

   As ‘S’ is a female in options (a) and (b), they can be rejected directly. The gender of ‘S’ in option (c) is not known, hence, it can also be eliminated. Now, check option (d).

   (c) is ruled out because we need two generation-change signs (– and ÷) between P and T. Same is the case with (a). Again, (d) is ruled out because P + Q does not give the sex of P.

   Correct Option: B

   (c) is ruled out because we need two generation-change signs (– and ÷) between P and T. Same is the case with (a). Again, (d) is ruled out because P + Q does not give the sex of P. Now, check (b)
