Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Phospholipids in the plasma membrane are arranged with their hydrophobic tails facing towards the aqueous outer surface. Reason (R): The nonpolar tails of saturated hydrocarbons require constant contact with water molecules to stabilize the lipid bilayer. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
