An attractive industry is one that is characterized by high entry barriers, suppliers and buyers with strong bargaining power, low threats from substitute products, and low rivalry among firms.?

suppliers and buyers with strong bargaining power is the odd one out here.

Explanation:

An attractive industry should be characterized by

high entry barriers suppliers and buyers with less bargaining power low threats from substitute products low rivalry among firms

Only the above listed characteristics can provide the best profit and make the industry attractive.

If the suppliers and buyers have strong bargaining power, then the industry will have only very less profit, since the bargaining power is more. Even if either a buyer or a supplier is strong enough to bargain it will lead to less profit only or in simple terms a loss to the industry.
