Explanation:

Let's match the List-I (Projects) with List-II (Beneficiary Districts):

- A. SIDHMUKH PROJECT ? Hanumangarh and Churu (iv)

- The Sidhmukh project mainly benefits Hanumangarh and Churu.

- B. NARMADA PROJECT ? Jalore and Barmer (i)

- Narmada canal waters are supplied to Jalore and Barmer.

- C. JAWAI PROJECT ? Jalore, Pali and Jodhpur (ii)

- Jawai dam serves irrigation in Jalore, Pali, and Jodhpur districts.

- D. JAKHAM PROJECT ? Udaipur and Pratapgarh (iii)

- Jakham dam is built for Udaipur and Pratapgarh.

So the correct matching is:

A-iv, B-i, C-ii, D-iii

Option 2 is correct.

- Option 1 (your answer) is: A-i, B-ii, C-iii, D- (not shown)

- This does not match the correct pairing as above.

- Sidhmukh ? Hanumangarh, Churu (iv)

- Narmada ? Jalore, Barmer (i)

- Jawai ? Jalore, Pali, Jodhpur (ii)

- Jakham ? Udaipur, Pratapgarh (iii)

Therefore, Option 2 is the correct one.
