  1. A1 and 2
  2. B2, 3 and 4
  3. C1, 3 and 4
  4. D1, 2, 3 and 4Correct

Explanation

The correct answer is D because all four plants mentioned can be successfully propagated through stem cuttings. Bougainvillea is commonly grown from semi-hardwood cuttings to maintain specific flower colors. Carnations are widely propagated using terminal stem cuttings in the floriculture industry. Cocoa is frequently multiplied through stem cuttings to ensure the genetic consistency of high-yielding varieties. Grapes are traditionally propagated using hardwood cuttings taken during the dormant season. Since vegetative propagation via stem cuttings is a viable and common method for all four plants, option D is the correct choice.
