Hey there!
A concrete noun is something people can see, touch, or basically use sense with.
Dog - This answer should be correct because you can use your senses with a dog. You can touch a dog with your hands and use your sense of touch.
Steve - This is a proper noun because this is a name of a person.
Wall - This is a common noun because it is just a thing/object.
Monica - This will also be a proper noun because it is someone's name.
Your final answer will be option A.
"Dog" is the concrete noun.
Hope this helps you.
Have a great day!
