(a) 1 and 2 only
(b) 3 and 4 only
(c) 1, 2 and 4 only
(d) 1, 2, 3 and 4
Answer: (c)
Explanation:
- Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice.
- Graphene is a two-dimensional material and has good electrical conduction.
- It is one of the thinnest but strongest materials tested so far.
It can be used for conducting electrodes required for touch screens, LCDs, and organic LEDs.
