Explanation:

Let’s break this down:

- Cow : Bull

- “Cow” is the female.

- “Bull” is the male.

- Mice : ?

- You want the male version of “Mice.”

- The singular is “Mouse.” But “Mice” is just the plural of “Mouse”—not a gender difference.

Let’s check the options:

- Cat: Not related by gender. Cat eats mice, but that’s not the point here.

- Fox: Same—a predator. Also, not a gender of “Mice.”

- Mouse: Just the singular of “Mice.” Not about gender.

- Dog: Predator, not a counterpart.

So what’s the right answer?

- The male of “Mice” (or “Mouse”) is actually just called a “Male Mouse”—there’s no special word for it, unlike “Bull” for “Cow.”

- None of the options give a gendered word like “Bull” does for “Cow.”

But, since “Mice” is plural, “Mouse” is singular, but not a gender distinction.

So the correct analogy isn’t possible with the given words. But based on the pattern, “Bull” is to “Cow” as male is to female. For “Mice,” none of the options are the masculine form.

Highlighting your answer:

- Option 3: Mouse

- Not the male form, just singular.

There’s actually no perfect fit here, but none of the other options are even close. If forced, Option 3 just shifts from plural to singular, not male to female, so it doesn’t match the relation given in the first pair.

What this really means is: among the options, none are correct in the way “Bull” is the male of “Cow.”
