Explanation:

The correct answer is option D, Wular Lake - Jhelum.

Wular Lake
Wular Lake is a large freshwater lake located in the Indian state of Jammu and Kashmir. It is one of the largest freshwater lakes in Asia and is situated between the cities of Srinagar and Bandipora. The lake is fed by the Jhelum River and other smaller rivers and streams.

Jhelum River
The Jhelum River is a major river in the Indian subcontinent, flowing through the Indian-administered territory of Jammu and Kashmir. It originates from the Verinag Spring in the Kashmir Valley and flows through the cities of Srinagar and Baramulla before entering Pakistan. In Pakistan, it merges with the Chenab River to form the Indus River.

Explanation of the Incorrect Pair
The pair Wular Lake - Jhelum is not correctly matched because Wular Lake is actually fed by the Jhelum River and not the other way around. The Jhelum River is the upstream source of water for Wular Lake, and the lake serves as a reservoir for the river.

Correctly Matched Pairs
a) Govind Sagar - Satluj: This pair is correctly matched. Govind Sagar is a reservoir located on the Satluj River in Himachal Pradesh, India. The reservoir was created by the Bhakra Dam, which is built on the Satluj River.

b) Kolleru Lake - Krishna: This pair is correctly matched. Kolleru Lake is a freshwater lake located in the Indian state of Andhra Pradesh. It is situated between the Krishna and Godavari River basins and is fed by the Krishna River.

c) Ukai Reservoir - Tapi: This pair is correctly matched. Ukai Reservoir is located on the Tapi River in the Indian state of Gujarat. It is one of the largest reservoirs in Gujarat and is used for irrigation, power generation, and drinking water supply.

Conclusion
In conclusion, the pair Wular Lake - Jhelum is not correctly matched because Wular Lake is fed by the Jhelum River and not the other way around. The other pairs - Govind Sagar - Satluj, Kolleru Lake - Krishna, and Ukai Reservoir - Tapi - are correctly matched.
