OPtion

1) 7826
2) 78254
3) 78054
4) 71754
5) 788264
6) 78874
7) 728224
8) 728814
9) 72834
10) None of these

Solution

Each lettter is coded as A=1, B=2. C=3 ....Z=26

Code is formed by: multiplication of highest number of each word - (Sum of highest number of each word)

So for TWINKLE TWINKLE LITTLE STAR = 23*23*20*19 - (23+23+20+20) = 211600 - 86

Similarly for LONDON BRIDGE IS FALLING = (15*18*19*14) - (15+18+19+14) = 71820 - 66 = 71754
