Answer 1

Answer: (a.)

Explanation:

It contains just enough functionality to talk to the parent node, and it cannot relay data from other devices.

Answer 2

Answer:

Option C is the correct answer.

Explanation:

Zigbee is an IEEE 802.15.4-based specified communication device designed for a group of high-end multiple user communication system  used to build personal communication networks with lower grade digital radios, such as for home security devices, data acquisition in hospitals/labs, and other places which needs wireless transmission and low grade digital output.

Therefore, Zigbee is low power producing wireless device used in various low power input devices to make seamless wireless communication possible.
