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)
Match List - I with List - II. 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)…

When a part of a straight capillary tube is placed vertically in a liquid, the liquid raises upto certain height $h$. If the inner radius of the capillary tube, density of the liquid and surface tension of the liquid decrease by $1 \%$ each, then the height of the liquid in the tube will change by $\%$.
