Wooden floor trusses are to be installed parallel with the partition wall (y's) making this walls, non-load bearing but acting as shearwall against N - S wind direction. Along shearwall line B, on the southern side, no shearwall can be provided due to architectural space requirement. Is it necessary to provide drag strut along line B on the southern side? thanks...

Would the diaphragm work if there is no shear wall along B at all? If it would, then I don't think that having a wall at B on only the northern side makes a worse case does it?
If the diaphragm relies on the shear wall at B on the northern side to work, then yes I would put in a drag strut.

A drag strut might possibly be used along B anyway to keep the B interference "soft" and not create any tears at the end of B.

The other walls should have boundary nailing called out on the plan in order for the shear to go to them and not fully to the outside walls.
A fully sheathed shearwall is significantly stiffer than a partition wall, therefore, that's where the load is going to go.
If you put a drag strut in and treat B as a shearwall, you'll have (approx) double the shear in it as the other two, thereby affecting your nail spacing and anchorage spacing.
