Given below are two statements: 
Statement I: Exudation of water droplets on the tips and edges of plant leaves is called guttation. It is caused by root pressure that forces more water to enter leaves than is transpired 
Statement II: Transpiration is a 'pulling' process, hence exploration of the rise of xylem sap by cohesion-tension mechanism begins not with roots but with leaves, where the driving force for transpirational pull begins 
In light of the above statements, choose the most appropriate answer from the options given below 
1. Both Statement I and Statement II are correct 
2. Both Statement I and Statement II are incorrect 
3. Statement I is correct but Statement II is incorrect 
4. Statement I is incorrect but Statement II is correct

Assertion(A): There is pulling of water, molecule by molecule, into the leaf from the xylem.
Reason(R): Evaporation of water through stomata facilitates the movement of water against gravity.
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.
