Percentage Error is a measurement of the discrepancy between an observed and a true, or accepted value.

According to Question,
% error =
× 100
= 2.631 % = 2.7 % (approximately.)
hope it helps!

There are two conditions necessary for total internal reflection, which is when light hits the boundary between two mediums and reflects back into its original medium:
Light is about to pass from a more optically dense medium (slower) to a less optically dense medium (faster).
The angle of incidence is greater than the defined critical angle for the two mediums, which is given by:
θ = sin⁻¹(/
)
Where θ = critical angle, = refractive index of faster medium,
= refractive index of slower medium.
Choice C gives one of the above necessary conditions.
