  2. BINR to GBP to USD to INR, gain Rs 40,000
  3. CINR to USD to GBP to INR, gain Rs 40,000Correct
  4. DNo gain, as rates are consistent

Explanation

Cross rate GBP/INR = 1.25 x 83 = 103.75, below Mumbai's 104.50, so GBP is dear in Mumbai: acquire GBP via USD. Rs 83,00,000 = USD 1,00,000 = GBP 80,000 (at 1.25). Sell at 104.50 = Rs 83,60,000, gain Rs 60,000. Recheck: 80,000 x 104.50 = 83,60,000. Gain is Rs 60,000, which is not listed; option 3 gives the correct route but the amount shown is wrong.
