c) Plunger
d) Pipe wrench

Final answer: The simplest plumbing tool with a brass weight used for vertical reference is a plumb bob.

Answer:

The simplest plumbing tool, consisting of a line with a brass weight on it is a plumb bob.

The plumb bob is a fundamental tool in plumbing that is used for establishing a vertical reference line, or plumb line. It consists of a line with a heavy brass weight attached to one end. When the plumb bob is suspended from a fixed point, the weight will ensure that the line is perfectly vertical, allowing plumbers to work with precision.

Answer (a) Plumb Bob is the correct choice. While the other options may be plumbing tools as well, they serve different purposes: a level is used to determine the horizontal plane, a plunger helps clear clogs in drains, and a pipe wrench is used for gripping and turning pipes.
