Which occurrence would contradict the big bang theory

The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.

Can you please give me more detail?

D. All of the above

Explanation:

A cartilaginous joint that is structurally amphiarthrotic in nature allows for slight movements in response to twisting and compression. The main function of cartilaginous joint is to permit to “give” upon these movements to prevent injury.

The symphyses refer to the joining of fibrocartilaginous pads and bones. These are also amphiarthrotic and flexible in nature allowing for slight movements in response to twisting and compression. The symphysis pubis and intervertebral disc joint allow for slight movements.

The synchondroses are also cartilaginous joints which have multiple hyaline cartilage layers arranged in between the adjoining bones.
