. . . . . dogs can make friendship with cats.

Understanding the Options:
* Few: This means *almost none* or *very few*, and it often implies a negative feeling.
* A few: This means *some* or *a small number*, and it has a more positive connotation.
* Little: This refers to an *amount* of something uncountable, like "little water" or "little time." We use it for things we can't count individually.
* A little: Similar to "little," this refers to a *small amount* of something uncountable.

Why other options are incorrect:
* Little and A little are wrong because we're talking about dogs, which are countable.
* Few is technically grammatically correct, but it suggests it's rare for dogs to befriend cats, which doesn't fit the usual meaning.

Why "A few" is the Best Answer:
* A few indicates that *some* dogs can be friends with cats. It's a reasonable and more positive statement.

So, the correct answer is B: A few because it is used to express some and also can be use with the count nouns.
