Solution

The correct option is B

49


Step 1: Given:

Collector current Ic=5.488mA

Emitter current Ie=5.60mA

Step 2: Formula used

The base current Ib=Ie-Ic

β=IcIb

Step 3: Finding base current

Ib=5.60-5.488

Ib=0.112mA

Step 4: Finding β

β=5.4880.112

β=49

⇒ The base current amplification factor is β=49

Hence, the correct answer is option B.
