Final Answer :
B
Explanation :
Studies have shown that if one identical twin has schizophrenia, there is approximately a 50% chance that the other twin will also be diagnosed with schizophrenia at some point in their life. This is because identical twins share 100% of their genetic material, making them more susceptible to the disorder if one twin has it. However, other environmental factors also play a role in the development of schizophrenia, which is why the likelihood is not at 100%.
