Lab Activity: Acid-Base Titration

Given below are two statements :
Statement (I) : Potassium hydrogen phthalate is a primary standard for standardisation of sodium hydroxide solution.
Statement (II) : In this titration phenolphthalein can be used as indicator.
In the light of the above statements, choose the most appropriate answer from the options given below:

Statement I: Potassium hydrogen phthalate is primary standard for $\mathrm{NaOH}$

Statement II : Phenolphthalein is used to detect completion of this titration.
