(iv). The industrialist and D and A are friend to one another but two of these prefer coffee to tea.
(v). The horticulturist is C`s brother.
Who is an industrialist ?
A prefers tea. So, from (iv), the industrialist and D prefer coffee. But, from (iii), B and the journalist prefer coffee. So, B is the industrialist and D is the journalist.
Now, A, C and advocate remain. Clearly, E is the advocate.
The horticulturist is C's brother. It can be only A. C is a physicist.
Hence, B is an industrialist.
