Solution

The correct option is D
$0.66$

Given,

Mass of a density bottle = $100 g$

Mass of density bottle + Mass of water = $175 g$

Mass of density bottle + Mass of oil = $150 g$

Mass of water = $75 g$

Mass of oil = $50 g$

Volume of water and oil is same

Relative density = $\frac{Density of oil}{Density of water}$ = $\frac{50}{75} = 0.66$
