Step 1: Recall the slogan.
The waste rule most students learn is Reduce, Reuse, Recycle. Hold these three words in mind and match them against each option.
Step 2: Count the matches.
Option 1 matches two words (Reduce, Reuse). Option 2 matches two words (Reuse, Recycle). Option 4 matches one word (Reuse). Option 3 matches all three words.
Step 3: Think about the meaning.
Return, Retire and Rescue are not waste handling steps in this rule. Only Reduce, Reuse and Recycle describe cutting waste, using again and making new material.
Step 4: Check the order.
Option 3 lists the words in reverse order. The question asks only for the three Rs, so the order does not matter.
Step 5: Pick the answer.
Option 3 is the only one with all three, so it is correct.
Step 6: Extra check.
For e-waste, Reduce means buying only what you need, Reuse means repairing or donating a device, and Recycle means sending it to an authorised centre. These are the three standard actions, so no other word fits in the list.
Final Answer:
The three Rs are Reduce, Reuse and Recycle, option 3.
\[ \boxed{\text{Option 3}} \]
