The question asks about TCS's total employee strength at the end of a quarter. The correct answer is 163,700 employees. The other options (2 lakhs, 5 lakhs, 10 lakhs) are incorrect - TCS employee count during this period was in the 100,000-200,000 range. This specific number would be from a particular quarter's results announcement. Note that 163,700 = 1.637 lakhs, which is less than 2 lakhs.
