Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In a metal the bonds are metallic which are non-directional. Hence the metal kernels can easily slide over another metal kernels within the lattice. The sea of electrons adjust themselves in the new lattice without any issues. Due to this metals can be made into thin sheets without breaking the metallic bonds and so they are malleable.

In metallic bonds are non directional since electrons are not shared with just one atom in a single direction, they are shared with many other neighbouring atoms in all directions
