It's not ____ cheap, but high quality too.

It's not ____ cheap, but high quality too.

• A. Only
• B. Really
• C. Just
• D. Merely

Answer: (A)

The main idea here is the not only… but construction, which is used to show two positive qualities at once with a strong contrast. The blank should be filled with only to form: It’s not only cheap, but high quality too. This makes clear that the item isn’t just cheap; it’s also of high quality. Why this fits best: not only cheap is the classic pairing that leads into the second clause with “but high quality too,” giving a natural, balanced contrast between low price and good quality. The other options would produce a less natural or different nuance—they don’t form the familiar idiomatic pattern as effectively.
