The total modulation index (βt) when a carrier wave is being modulated by two modulating signals can be calculated using the formula:

βt = sqrt(β1^2 + β2^2)

where β1 and β2 are the modulation indices of the two signals.

In this case, β1 = 0.8 and β2 = 0.3.

So, βt = sqrt((0.8)^2 + (0.3)^2)
= sqrt(0.64 + 0.09)
= sqrt(0.73)
= 0.8544

So, the total modulation index is 0.8544. Therefore, the correct answer is a. 0.8544.
