Which technology category would not likely be the subject of a standard published by the international electrotechnical commission (iec)?

a. semiconductors
b. solar energy
c. encryption
d. consumer appliances

Encryption would not likely be the subject of a standard published by the International Electrotechnical Commission (IEC).

Option C

Explanation:

IEC (International Electrotechnical Commission) is the world's number one organization that develops and releases international standards for all electronic-electrical technologies and its affiliates.

Its standards would cover a wide technology range, from energy generation, transmissions and distributions to house appliances and offices, semiconductors, batteries, fibreglass, solar energy, Nano-technology and sea energy and many more.

IEC standards apply to all electrical technologies, including electronics, magnets and electro-magnetics, electro-acoustics, multi-media, telecommunications, and medical technologies, as well as related general fields such as terminology and symbols, etc.
