The correct answer is: B. Increasing the width.
Transconductance is the ratio of the change in drain current to the change in gate voltage. It is a measure of how much current a transistor can source or sink for a given change in gate voltage.
The transconductance of a transistor can be increased by increasing the width of the channel. This is because a wider channel has more carriers available to be moved by the gate voltage.
The other options are incorrect because they would decrease the transconductance of the transistor.
- Decreasing the width of the channel would decrease the number of carriers available to be moved by the gate voltage. This would decrease the transconductance.
- Increasing the length of the channel would increase the resistance of the channel. This would decrease the current that can be sourced or sunk for a given change in gate voltage. This would decrease the transconductance.
Therefore, the correct answer is B. Increasing the width.
