One million $=$Ten lakh.

Ten million $=$One crore.

One billion $=$One hundred crore.

Ten billion $=$ One thousand crore.

Explanation for $\left(A\right)$.

So, three hundred thousand will be three lakh.

Therefore, $\left(A\right)$ matches to $\left(iv\right)$.

Explanation for $\left(B\right)$

We know that, One billion$=$One hundred crore.

So, three billion will be three hundred crore.

Therefore, $\left(B\right)$ matches to $\left(iii\right)$.

Explanation for $\left(C\right)$

We know that, Ten million$=$One crore.

So, thirty million will be three crore.

Therefore, $\left(C\right)$ matches to $\left(i\right)$.

Explanation for $\left(D\right)$

We know that, One million$=$Ten lakh.

So, three million will be thirty lakh.

Therefore, $\left(D\right)$ matches to $\left(ii\right)$.
