Correct Answer: Option (D) — 1, 2, 3 and 4 only

Concept & Option Breakdown

Standard Reference Verified

Stem cutting is a vegetative propagation technique where a portion of a stem containing nodes and buds is cut and rooted:

  • Bougainvillea: Readily multiplied through hardwood or semi-hardwood stem cuttings.
  • Carnations: Commercially propagated via terminal stem cuttings taken from healthy side shoots.
  • Cocoa (Theobroma cacao): Propagated clonally using semi-hardwood stem cuttings to preserve elite genotypes.
  • Grapes (Vitis vinifera): Standard commercial propagation is via dormant hardwood stem cuttings.
Elimination Heuristic & Exam Approach

All four are commercial horticultural/cash crops where vegetative propagation via stem cuttings is standard practice to preserve cultivar genetics.
