The change in collector current can be calculated using the formula:

ΔIc = β x ΔIb

where ΔIc is the change in collector current, β is the current gain of the transistor, and ΔIb is the change in base current.

Given that the current gain of the transistor is 100 and the base current changes by 200 A, we can substitute these values into the formula to find the change in collector current.

Explanation:

1. Calculate the change in collector current:
ΔIc = β x ΔIb
ΔIc = 100 x 200 A
ΔIc = 20,000 A

2. Convert the change in collector current to milliamperes (mA):
ΔIc = 20,000 A = 20,000 x 10^3 mA
ΔIc = 20,000,000 mA

3. Answer:
The change in collector current is 20,000 mA, which can be written as 20 mA.

Therefore, the correct answer is option D) 20 mA.
