Consider the following statements:1. The sweet orange plant is propagated by grafting technique.2. The Jasmine plant is propagated by layering technique.Which of the statements given above is/are correct?

a1 only
b2 only
cBoth 1 and 2
dNeither 1 nor 2
✓ Correct answer: c) Both 1 and 2
ExplanationStatement 1 is correct: The sweet orange plant is propagated through the grafting technique where a scion (shoot) from a desired sweet orange tree is grafted onto the rootstock of a compatible plant.This ensures the plant retains the desired traits such as high fruit quality and disease resistance.Statement 2 is correct: The jasmine plant is commonly propagated by layering technique, particularly mound layering or air layering.This method involves bending a healthy branch to the ground or wrapping it with moist materials to encourage root development, which helps maintain the plant’s genetic identity and growth potential.UPSC GS Paper-I PYQs 614 379
