Assertion: Silicones are water-repelling in nature.

Reason: Silicones are organosilicon polymers, which have (-R2SiO-) as repeating units.

1.  Both assertion and reason are true and the reason is the correct explanation of assertion.

2.  Both assertion and reason are true, but the reason is not the correct explanation of assertion.

3.  Assertion is true but the reason is false.

4.  Assertion is false but the reason is true.

Hint: Silicones being surrounded by non-polar alkyl groups are water-repelling in nature
Silicones are a group of organosilicon polymers that have (R2SiO) as a repeating unit. This suggests that silicones are
surrounded by non-polar alkyl groups that are water-repelling in nature. They have wide applications. It is used for
waterproofing of fabrics.
Hence, both Assertion and Reason are true and the Reason is not the correct explanation of Assertion.
