Which Is the Most Appropriate Acid-Base Indicator to Use in the Titration

Which is the most appropriate acid-base indicator to use in the titration of 0.100 molar ammonia solution by 0.100 molar HCl(aq) ?

A) thymol blue, for which pK_In = 8.8; HInd is yellow and Ind^- is blue
B) methyl orange, for which pK_In = 3.8; HInd is red and Ind^- is yellow
C) thymolphthalein, for which pK_In = 9.9; HInd is colorless and Ind^- is blue
D) cresol red, pK_In = for which 7.9; HInd is yellow and Ind^- is red
E) All of the indicators listed will work equally well for the titration of a weak acid by a strong base.
