Find the incorrect part of the sentence:
The sceneries of Ooty were wonderful.

Correct option is B

Option (b) contains an error.
Explanation: The noun scenery is an uncountable (non-count) noun; it does not take a plural form ( sceneries ✗). We should use The scenery of Ooty was wonderful or better The scenery in Ooty was wonderful.
Grammatical rule used: Uncountable nouns (e.g., scenery, furniture, information, advice, luggage) do not take plural –s and generally take a singular verb.
Example:
• The scenery of Kashmir is breathtaking. (✓)
• The sceneries of Kashmir are breathtaking. (✗)
Info booster / exceptions: When we want to express variety, we can use structures like kinds of scenery or beautiful scenes (countable scene, not scenery).
