I'll be glad to check your answer.

The correct sentence that uses possessive nouns correctly is option A: "The two brothers’ invention was a children’s game; each player’s marker was an animal."

Here's an explanation for each choice:

A. The two brothers’ invention was a children’s game; each player’s marker was an animal.
- This sentence correctly uses the possessive form for "brothers" and "player".
"Brothers'" is used as a possessive form to indicate that the invention belongs to the two brothers.
"Player’s" is used as a possessive form to indicate that the marker belongs to each player.

B. The two brother’s invention was a childrens’ game; each player’s marker was an animal.
- This sentence has an error with the use of the possessive form.
"Brother’s" should be "brothers'" to indicate that the invention belongs to both brothers.
"The childrens’ game" is incorrect as it should be "children’s game" to indicate that the game is meant for children.

C. The two brother’s invention was a children’s game; each players’ marker was an animal.
- This sentence has an error with the use of the possessive form.
"Brother’s" should be "brothers’" to indicate that the invention belongs to both brothers.
"Players’" is also incorrect as it should be "player’s" to indicate that the marker belongs to each player.

D. The two brothers’ invention was a childrens’ game; each players’ marker was an animal.
- This sentence has multiple errors with the use of the possessive form.
"Brothers’" is correctly used to indicate the invention belongs to the two brothers.
"Childrens’" is incorrect as it should be "children’s" to indicate that the game is meant for children.
"Players’" is also incorrect as it should be "player’s" to indicate that the marker belongs to each player.

So, the correct sentence that uses possessive nouns correctly is option A.

Nope.

Hint: if there are two brothers, is that singular or plural? And each player is one person, isn't s/he?

soooo....A?

Yes, A.
