List - I (Number)		List - II (Signficant figure)
(A)	$1001$	(I)	$3$
(B)	$010.1$	(II)	$4$
(C)	$100.100$	(III)	$5$
(D)	$0.0010010$	(IV)	$6$

Choose the correct answer from the options given below:

Rules for significant figures:

1. All non-zero numbers are significant

2. Zeros between two non-zero digits are significant

3. Leading zeros are not significant

4. Trailing zeros to the right of the decimal are significant

5. Trailing zeros in a whole number with the decimal shown are significant

6. Trailing zeros in a whole number with no decimal shown are not significant

From above rule, we get

(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
