The correct option is
A Branches
Layering: In this method, a branch of the plant is pulled towards the ground and a part of it is covered with moist soil leaving the tip of the branch exposed above the ground. After some time, new roots develop from the part of the branch buried in the soil. The branch is then cut off from the parent plant. The part of the branch which has developed roots grows to become a new plant (just like the parent plant). Jasmine plant (chameli) is propagated or produced by the layering method. We can see from that one left side branch and one right side branch of the parent jasmine plant have been buried in moist soil. The parts of branches which are buried in soil grow their own roots. When this happens, the branches of the parent plant connecting the newly formed plants are cut off so that the newly formed plants may grow on their own and develop into mature plants (like the parent plant). Jasmine cannot be propagated by flowers, seeds or stem
So, the correct answer is 'Branches'
