  1. X1: A =H , B = bond, C = (b) under B which is halo substituted phenylene which completely matches with 4th position substituent of the generic compound
  2. X2: D = (b) under B is a phenylene(implies a substituted aryl) and F-C- is a substituent on D. It is clear that this will match with R2 (substituent aryl) at the 5th position of pyrazole of the generic structure
  3. X3: R1 = Q(alkyl) which matches with R1(alkyl) at the 1st position of pyrazole of the generic structure
