C is the answer because he wants to know if less force is needed to pull on a slippery surface which reduces friction
Four different substituents are required on a carbon atom for it to be chiral.
<h3>What is Chiral Carbons ?</h3>
The carbon atom which is attached with four different types of group of atoms or atoms is called Chiral carbon. Chiral molecules are non superimposable on their mirror images. Chiral carbon is also called asymmetric carbon.
Example:

In the above example we can see that carbon atom has 4 different group attached with it that is Br, Cl, H, CH₃.
Thus from the above conclusion we can say that Four different substituents are required on a carbon atom for it to be chiral.

<span>In water, naoh almost completely separates into na+ and oh- ions. thus, naoh is Stong base.
Strong bases and strong acids completely ionized in the water,So when NaOH is added into water, it is completely ionized and forms Na+ and OH- ions and it shows that it is a strong base.</span>
