B

943 129 815

C

195 831 498

D

Soln.
Ans: a

'647' is common to items 2 and 3. So '647' = 'abroad'. Next we can see that '496' is common to items 1 and 2. So '496' = 'news'. Again we can see that '632' is common to items 3 and 4. So '632' = 'people'. Hence 'abroad news people' should be from '647 496 632'
