Correct Answer is B

Explanation

When using multiple eye drops, it's generally recommended to wait at least 5 minutes between administering each medication. This helps prevent dilution of the medication and improves its absorption.
A is incorrect because holding pressure on the conjunctival sac after administering eye drops is not necessary and may increase systemic absorption of the medication.
C is incorrect because contact lenses should typically be removed before administering eye drops to prevent interference with the medication reaching the eye.
D is incorrect because touching the tip of the dropper to the sclera of the eye can contaminate the dropper tip and increase the risk of infection. It's important to administer eye drops without touching the tip to the eye or any other surface.
