Two identical charged spheres are suspended by strings of equal lengths. The strings make an angle of $37^\circ$ with each other. When suspended in a liquid of density $0.7 \, \text{g/cm}^3$ , the angle remains the same. If the density of the material of the spheres is $1.4 \, \text{g/cm}^3$ , the dielectric constant of the liquid is:

A
$1$
B
$2$
C
$3$
D
$4$
