Step 1: Recall the rule.
Every rasa has one fixed sthayi bhava. We test each pair against this list from the Natyashastra.
Step 2: Make a quick list.
Love gives Rati. Sorrow gives Shoka. Energy gives Utsaha. Anger gives Krodha. Fear gives Bhaya. The first three match pairs A, B and C directly.
Step 3: Test pair D.
Pair D joins Raudra with Bhaya. Raudra means fury, and its emotion is anger (Krodha). Fear belongs to Bhayanaka. So D is a mismatch.
Step 4: Compare with the choices.
Options (1), (3) and (4) include D, so they cannot be right. Option (2) contains exactly A, B and C.
Step 5: Conclude.
Option (2) is the answer.
Final Answer:
Option (2) is correct.
\[ \boxed{\text{2}} \]
