—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 commonly used to politely grant permission or express willingness, perfectly fitting the context of someone asking to look at a book.

Let’s analyze the options:

A. By this means (通过这种方式) refers to a method or approach, not permission.

B. By all means (当然可以) is the natural response to a request for permission, indicating agreement.

C. By this way is grammatically incorrect; the proper phrase is "in this way" (以这种方式).

D. By any means (无论如何) emphasizes using any method necessary, which doesn’t fit the context of granting permission.

Next time someone asks to borrow your book, you’ll know exactly which phrase to use!
