I feel like dumbass now! Finally I was able to do the Option B and replace the Switch.

When I was putting all back I stripped a Brake line connector hole and the nut on the ABS Module. I guess I was tired and upset and didn't realized the thread was going in Wrong. It's on of the closer lines from Master Cylinder to the ABS Module. Attached photo.

I think I need to take it out, re-thread the hole, replace the Line (may be able to use it with some sort of vise.

Would appreciate any suggestion. this sucks!
