🧠 Classroom Explanation

Let us verify each row carefully.

---

🔹 Row 1: Dhuandhar – Malwa – Narmada ❌

• Dhuandhar Falls:
  • Located near Jabalpur, Madhya Pradesh
  • Formed by the Narmada River
• However:
  • Jabalpur lies in the Mahakoshal region
  • Not in the Malwa Plateau
• Malwa lies north-west of Vindhya Range
• Mahakoshal lies south of Vindhya Range

✔️ River is correct
❌ Region is incorrect

✘ Row 1 is incorrectly matched

---

🔹 Row 2: Hundru – Chota Nagpur – Subarnarekha ✅

• Hundru Falls:
  • Located near Ranchi, Jharkhand
  • Lies on the Subarnarekha River
• Ranchi is part of the Chota Nagpur Plateau
• Hundru is the highest waterfall in Jharkhand

✔️ Region correct
✔️ River correct

✅ Row 2 is correctly matched

🔹 Row 3: Gersoppa – Western Ghats – Netravati ❌

• Gersoppa (Jog) Falls:
  • Formed by the Sharavathi River
  • Located in Shimoga district, Karnataka
  • Lies in the Western Ghats

📊 Final Assessment

Row	Status
Dhuandhar – Malwa – Narmada	❌
Hundru – Chota Nagpur – Subarnarekha	✅
Gersoppa – Western Ghats – Netravati	❌

👉 Only one row is correctly matched

---

❌ UPSC Elimination Logic

• UPSC exploits:
  • Physiographic region confusion (Malwa vs Mahakoshal)
  • River–waterfall mismatch (Sharavathi vs Netravati)
• Partial correctness is not accepted

---

🧩 Memory Hook

“Jog falls with Sharavathi, Hundru rides Subarnarekha — Malwa stays away.”

🧠 Prelims Strategy Insight

For waterfall questions:

• Always remember:
  • Region first
  • River second
• Western Ghats waterfalls are short, steep, west-flowing
• Plateau waterfalls are older and broader
