Which of the following is non-metal and can be malleable?

The ability to transform into another shape without breaking is referred to as malleability. An example of this is the malleability of clay. With the aid of clay as an example, which is soft and can be easily molded into any shape, we can easily comprehend the term malleability. All metals are malleable, however, non-metals are typically not.

Physical malleability can be interpreted as the quality of anything being able to be worked, pounded, or molded without breaking. Plasticity and malleability are related terms.
Except for graphite, all of the alternatives are gases. Because it contains non-metal carbon graphite is an allotrope of carbon. Carbon is in sp² hybridization in graphite. Layers of graphite make up the solid structure. Because of the weak intermolecular interactions, graphite is soft and the layers can glide over one another. This makes it simple to flatten. Graphite is hence non-metal and malleable.
Keep in mind that under high pressure and temperature, graphite transforms into a diamond. Both lubricants and pencils include graphite. Even though it is not a metal, it nonetheless conducts heat and electricity well. Solar panels, batteries, and electrodes are a few examples of electronic items that utilize them.

Hence, the correct answer is option A.
