Explanation

Graphene is renowned for its excellent electrical conductivity, which stems from its two-dimensional, one-atom-thick structure.

Graphene is famously strong for its very thin structure, making it one of the strongest materials known.

Graphene is made entirely of carbon, arranged in a hexagonal lattice. While it does have high optical transparency, its composition is carbon, not silicon.

Its electrical conductivity, along with its optical transparency, makes graphene an excellent candidate for use in conducting electrodes for various display technologies.

So, statements 1, 2 and 4 are correct.
