The correct answer is: A few.
The word “a few” means “a small number of”. In this case, the question is asking how many alphabets are readable in the book. The answer is “a few” because there are only a small number of alphabets that are readable in the book.
The other options are not correct because they do not accurately describe the number of alphabets that are readable in the book. The word “much” means “a large amount of”. The word “a little” means “a small amount of”. The word “how many” is a question that asks for a specific number.
Here is a table that summarizes the correct and incorrect answers:
| Option | Meaning | Correct? |
|—|—|—|
| A few | A small number of | Yes |
| Much | A large amount of | No |
| A little | A small amount of | No |
| How many | A specific number | No |
