Sensitivity increases with decrease in viscosity of the liquid.

Sensitivity = d|r.

Sensitivity of liquid is depend on viscosity.

@Radha.

Thanks for giving the correct explanation.

The correct option is B.

Sensitivity is L/R which means it is directly proportional to the length and inversely proportional to the radius of curvature soo A is the correct answer.

Option D is completely wrong as they are directly proportional to sensitivity.

I think due to increase in viscosity and surface tension, the length of the bubble decreases (as the liquid tends to become more spherical shape). Since the length of bubble decreases, the sensitivity also decreases. So, option D is correct.
