C. `A to d, B to a, C to b, D to c`
D. `A to d, B to b, C to c, D to a`

Answer

C

Explanation

A -d " " When a body with density more than the density ofliquid is immwesed, 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 1000` " g "
One quintal = `10^(5)` " g ' C-b " "One tonne = 1000 kg
But one kg = 1000 " g "
And one g = 1000 mg
`:.` One tonne = `1000xx 1000xx 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 unit of pressure.
