Solution:

Given data:

Return Ratio = 24

Feedback Factor = 3

Change in open loop gain = 2

Relative change in gain with negative feedback = ?

Formula used:

Relative change in gain with negative feedback = ΔA / (1 + Aβ)

Where,

ΔA = Change in open-loop gain

A = Open-loop gain

β = Feedback factor

Calculation:

From the given data, we know that

Return Ratio (R) = 1 / β

=> β = 1 / R

= 1 / 24

= 0.0417

Now, let's calculate the open-loop gain (A).

We know that A = R * (1 + β)

= 24 * (1 + 0.0417)

= 24.9992

The change in open-loop gain (ΔA) = 2

Using the formula, we can calculate the relative change in gain with negative feedback.

Relative change in gain with negative feedback = ΔA / (1 + Aβ)

= 2 / (1 + (24.9992 * 0.0417))

= 0.01

Therefore, the relative change in gain with negative feedback is 0.01.

Hence, the correct option is (d) 0.01.

F = A/(1+Aβ)
Aβ = 24
A = 8
Relative change in gain = dAF/AF = dA/A(1+Aβ)
dAF/AF = 2/8*25 = 0.01.
