I have just seen your advertisement ¾ a Chinese book.

ক. on

খ. about

গ. of

ঘ. for

উত্তর: for

ব্যাখ্যা: Option A: on — “On” is used for platforms or media, e.g., on TV, on the website, on the notice board. — Here, the sentence is about what the advertisement is promoting, not where it appears Option B: about — “About” means what the ad talks about or concerns the topic. — Grammatically correct, but in most exam contexts, “advertisement for [something]” is expected because ads usually promote or sell something. Option C: of — “Of” is not used with advertisement in this context. — We don't say “advertisement of a book” in standard English. Option D: for — “For” shows purpose / promotion / offering. — Perfectly fits the usual meaning: the ad promotes or sells the book.
