Assertion $(A)$ : Silicons are water repelling in nature.
Reason $(R)$ : Silicons are organosilicon polymers, which have $\left(\mathrm{R}_2 \mathrm{SiO}{-}\right)$ as repeating unit.
  • A
    $A$ and $R$ both are correct and $R$ is the correct explanation of $A.$
  • Both $A$ and $R$ are correct but $R$ is not the correct explanation of $A.$
  • C
    $A$ and $R$ both are not true.
  • D
    $A$ is not true but $R$ is true.

Answer

Correct option: B.
Both $A$ and $R$ are correct but $R$ is not the correct explanation of $A.$
Silicones are organosilicon polymers and they are hydrophobic in nature.
Silicones neither react nor absorb water molecules.
