Who is an industrialist?

Options

A. E
B. C
C. B
D. D

Answer

C

Explanation

The information can be summarised as follows:
A cannot be an advocate and prefers tea.
C cannot be an advocate and prefers tea.
An advocate prefers tea.
B cannot be a journalist and prefers coffee.
The journalist prefers coffee.
A cannot be an industrialist but prefers tea.
So, the industrialist prefers coffee.
D, who cannot be an industrialist, prefers coffee.
Since the journalist prefers coffee, so D, who cannot be an industrialist and prefers coffee, is the journalist.
Also, the industrialist prefers coffee. So, B, who cannot be a journalist, will be the industrialist. Now, A and C will be the horticulturist or the physicist but C cannot be the horticulturist. So, A will be the horticulturist and C will be the physicist. Thus, the remaining person,
E, will be the advocate.
B is the industrialist.
