Step 1: Reaction
Saponification: 1 mole of Triglyceride + 3 moles of $NaOH \rightarrow$ 3 moles of Soap + 1 mole of Glycerol.
Step 2: Mole Ratio
The stoichiometry between triglyceride and glycerol is 1:1.
Step 3: Analysis
If $n$ moles of triglyceride react, then $n$ moles of glycerol are produced.
Step 4: Conclusion
The answer is $n$.
Final Answer:(A)
