Question

Statement: The oceans are a storehouse of practically every mineral including uranium. But like most other minerals, it is found in extremely low concentration -about three gms per 1000 tonnes of water.
Conclusions: I. The oceans are a cheap source of uranium.
II. The oceans harbour radiation hazards ___________.

• A. if only conclusion I follows
• B. if only conclusion II follows
• C. if either I or II follows
• D. if neither I nor II follows

Answer 1

The correct option is D if neither I nor II follows

I can not be concluded as most of the minerals are available in similar concentration levels in oceans. II is out of context of the sentence.
