Detailed Solution

Concept: The word given here is luminous, which implies very bright or something shiny, hence the right option is that option 1, dark which means having no light and has the correct opposite meaning of the word luminous.
In option 2, ludicrous means being unreasonable.
In option 3, unsteady means shaking or moving.
In option 4, provoking means causing a positive or a negative reaction, especially a negative one.
These options are incorrect because they do not express any opposite meaning of the given word for choosing an antonym. They need their own significant and specific meaning which in any given terms doesn't relate to luminous.
Sometimes one might get confused while finding the proper antonym because the given word can have different antonyms. But in this question option 1 is the absolutely correct answer.
Hence, the correct answer is option 1.
