ACSR conductors are universally employed for distribution systems (feeders as well as distributors), AAC can be used for distribution purpose provided the spans are small.
Hence, statement-1 is false.
The conductor size for a feeder is mainly governed by current carrying capacity and overall economy. Hence, 2 is also a false statement.

The correct answer is option 'C' - none.
Let's analyze each statement individually:
1. AAC (All Aluminium conductors) are universally employed for feeders as well as distributors.
This statement is not true. While AAC conductors may be used in some cases for feeders and distributors, they are not universally employed. Other types of conductors like ACSR (Aluminium Conductor Steel Reinforced), AAAC (All Aluminium Alloy Conductor), and even copper conductors can also be used for feeders and distributors depending on the specific requirements of the application.
2. The conductor size for a feeder is mainly governed by the permissible voltage drop in the line.
This statement is also not true. While the permissible voltage drop in the line is an important factor to consider in determining the conductor size, it is not the only governing factor. Other factors such as the maximum current carrying capacity of the conductor, the temperature rise of the conductor, and the short-circuit current rating of the conductor also need to be taken into account when selecting the appropriate conductor size for a feeder.
In summary, neither statement is true. AAC conductors are not universally employed for feeders and distributors, and the conductor size for a feeder is not solely governed by the permissible voltage drop in the line.
