This is referred to as critical race. That is a change in two input variables that results in an unpredictable output value for a bis-table device like this SR flip flop.

When both S=1 and R=1 the occurrence of a clock pulse causes both outputs to go to 0 (zero) and when the pulse is removed the state of the flip-flop is indeterminate or invalid as shown in answer B.
