Hint:The electric power line enters our house through three wires-namely the live wire, the neutral wire and the earth wire. To avoid confusion we follow a color code for insulating these wires.
Complete step by step answer:
-The wires enter the building with colors to avoid the confusions for insulating these wires. The red wire is the live wire, and the black wire is neutral. The earth wire is given green plastic insulation.
-Tai Sin started wire production in 1980 in Singapore which manufactured, distributed, and serviced various electrical components including cables and wires, as well as testing and inspection systems. The colour codes for electrical wires are different in several countries. Each country has its manufacturers for the manufacturing of the wires for electricity and therefore the color coding for the wiring is about by the government organization which is followed throughout the country by all manufacturers.
The color coding of wires is green for earth, red for live and black for neutral so, option A is a correct option.
Note:The various color coding schemes for wires are wont to identify the various categories of wires from a bulk of wires. For instance if same color coding is employed for overall wiring then it'll be difficult to spot the neutral, live or earth wire. The colour coding of cables is different in several countries for U.K, neutral wire is represented by blue color, main or the eager beaver is represented by brown and therefore the earth cable or wire is represented by green and yellow. There are two color codes for wires in Singapore.
