Match the following

Options

A. A-a, B-b, C-c, D-d
B. A-d, B-c, C-b, D-a
C. A-d, B-a,C-b, D-c
D. A-d, B-b, C-c, D-a

Answer

C

Explanation

A-d : When a body with density more than the density of liquid is immersed, the volume of the displaced liquid is equal to the volume of the solid.
B-a : One quintal =100 kg
But one kg =1000 g
One quintal `=100 xx 1000g`
One quintal `=10^(5)g`
C-b One tonne=1000 kg
But one kg =1000 g
One tonne `=1000 xx 1000g`
And one `g=1000 mg`
One tonne `=1000 xx 1000 xx 1000 mg`
One tonne `=10^(9) mg`
D-c : `"kgwt m"^(-2)="kgwt/m"^2`
kgwt is unit of force and `m^2` is unit of area.
Force per unit area is called pressure.
`"kgwt m"^(-2)` is the unit of pressure.
