Solution

The correct option is C $7.1$
Given: Density of the substance: $7100 k g / m^{3}$ , Density of water at $4^{o} C$ = $1000 k g / m^{3}$

$R e l a t i v e d e n s i t y = \frac{D e n s i t y o f s u b s t a n c e}{D e n s i t y o f w a t e r a t 4^{o} C}$

$= \frac{7100}{1000} = 7.1$

Hence, option C is correct.
