Option 1 is incorrect because it pairs AT&T, a telecommunications company, with wind energy, which is not a relevant product to AT&T.

Option 2 is incorrect because it pairs Chevron, an energy corporation, with micro-processors, and AMD, a semiconductor company, with oil which are incorrect associations.

Option 3 is the correct answer. Chevron is an oil company (A-2), AT&T is a telephone and an internet service provider (B-3), AMD is known for its microprocessors (C-4), and Enercon GmbH is a wind energy company (D-1).

Option 4 is incorrect because it assigns Chevron to micro-processors and AT&T to wind energy, which are inappropriate matchups for these companies. Similarly, AMD and Enercon GmbH are also inappropriately matched with oil and telephone/internet services respectively.
