—May I have a look at your book? —_____. [ ] A. By this means B. By all means C. By this way D. By any means

The correct answer is B. By all means. This phrase is a polite and enthusiastic way to grant permission, meaning "certainly" or "of course."

Let’s analyze the options:

A. By this means refers to "using this method," which is irrelevant to responding to a request to look at a book.

C. By this way is grammatically awkward and not a standard phrase for granting permission.

D. By any means typically means "at all costs" (e.g., "I’ll finish by any means"), which doesn’t fit the context of politely agreeing.

In conversational English, "By all means" is the natural response when someone asks to borrow or examine something. It conveys willingness without sounding overly formal. When someone asks to look at your book, this phrase clearly signals, "Yes, feel free."
