The correct answer is: B. Lower horizontal wooden member
The sill is the lowest horizontal member of a frame or structure, typically resting on the ground or another support. In the case of a common wooden partition, the sill is the lower horizontal wooden member that supports the vertical members.
The other options are incorrect because:
- Option A: The vertical wooden members on either end of a common wooden partition are called studs.
- Option C: The upper horizontal wooden member of a common wooden partition is called the header.
- Option D: The intermediate horizontal wooden member of a common wooden partition is called the soleplate.
