Correct option is B. $$10$$ lakh
We know that $$1$$ million $$= 1,000,000$$
$$= 10,00,000$$ in Indian system
And $$1$$ lakh $$= 1,00,000$$
Now $$1$$ million $$ = 1,000,000$$
$$=10, 00,000$$
$$= 10 \times 1,00,000$$
$$= 10$$ lakhs
Therefore, $$1$$ million $$= \underline{10}$$ lakhs
$$\therefore$$ $$\textbf{Option B is correct}$$.
