The correct answer is: C. Rectangular
A termination indication board is a type of electrical panel that is used to indicate the termination points of electrical wires. It is typically made of a rectangular piece of metal or plastic, and it has a number of holes drilled into it. The wires are then terminated in the holes, and the board is labeled with the name of the wire and the circuit that it is connected to.
A square termination indication board would be inefficient, as it would waste space. A round termination indication board would be difficult to label, as the labels would be difficult to read. Therefore, a rectangular termination indication board is the most efficient and practical option.
Here are some additional details about each option:
- Square: A square termination indication board would be inefficient, as it would waste space. The corners of the board would not be used, and the wires would have to be routed around them. This would make the board more difficult to install and would increase the risk of damage to the wires.
- Round: A round termination indication board would be difficult to label, as the labels would be difficult to read. The wires would also have to be routed around the circumference of the board, which would make the board more difficult to install and would increase the risk of damage to the wires.
- None of these: None of the options listed are correct. The correct answer is: C. Rectangular
