Step 1: Understand the task. This is a matching question. We pair each role in List-I with the correct mineral element in List-II. The trick is to remember what each element does inside a plant.
Step 2: Element for growing tissue. Item I talks about meristematic tissue, the part of the plant that keeps dividing and growing. Nitrogen ($N$) is the main element needed here because it builds proteins and nucleic acids for new cells. So I goes with D (Nitrogen).
Step 3: Element that activates respiration and photosynthesis enzymes. Item II asks for an enzyme activator for respiration and photosynthesis. Magnesium ($Mg$) sits at the centre of chlorophyll and switches on many such enzymes. So II goes with A (Magnesium).
Step 4: Element for electron transfer. Item III mentions electron transfer through ferredoxin and cytochrome. Iron ($Fe$) is the metal inside these carriers, so it passes electrons easily. So III goes with E (Iron).
Step 5: Element that activates IAA oxidase. Item IV asks for the activator of the IAA oxidative enzyme. Manganese ($Mn$) is known to activate this enzyme. So IV goes with B (Manganese).
Step 6: Combine and match the option. Putting it together we get I-D, II-A, III-E, IV-B. This exactly matches the first option. \[ \boxed{\text{I-D, II-A, III-E, IV-B}} \]
