Question

Match the following lists

• A. A-III, B-I, C-IV, D-II
• B. A-II, B-IV, C-I, D-III
• C. A-II, B-III, C-I, D-IV
• D. A-I, B-II, C-IV, D-III

Hint:

2,4-D is highly selective. It targets and kills dicot weeds while leaving monocot grasses unharmed, making it the most popular lawn herbicide.

Answer 1

The Correct Option is A

Step 1: Anchor on two pairs you can be sure of.
Ethylene is well known for breaking dormancy, particularly in sprouting potato tubers, so that item goes with the dormancy-breaking function. Gibberellins are equally well known for bolting, the sudden shooting up of rosette plants like cabbage, so that item goes with bolting.
Step 2: Filter the four options using just these two links.
Drop any option where the ethylene item is not paired with dormancy breaking, or where the gibberellin item is not paired with bolting.
Step 3: See what survives.
Only one listed combination keeps both of these pairs together, and it also carries the remaining two matches along with it.
Final answer: Option 1, A-III, B-I, C-IV, D-II.
