Concept:
Vegetative propagation methods vary with plant species and plant parts used for multiplication.
Step 1: Match Offsetting.
Pineapple can be propagated through offsets.
\[
A\rightarrow IV
\]
Step 2: Match Scaling.
Scaling is used in bulbous plants and is matched with gladiolus in the given list.
\[
B\rightarrow II
\]
Step 3: Match Division.
Ferns are commonly propagated by division.
\[
C\rightarrow I
\]
Step 4: Match Layering.
Jasmine is commonly propagated by layering.
\[
D\rightarrow III
\]
Therefore:
\[
A-IV,\ B-II,\ C-I,\ D-III
\]
\[
\therefore \text{Correct Answer is (B)}
\]
