Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]:

Assertion: The association constant in water for the G-C base pair is three times lower than that for the A-T base pair.

Reason: There are three hydrogen bonds in the G-C base pair and two in the A-T base pair.

1. Both [a] and [r] are true and [r] is the correct reason for [a]
2. [a] is false but [r] is true
3. Both [a] and [r] are false
4. Both [a] and [r] are tme and [r] is not the correct reason for [a]
