Answer:
A). Self-serving bias.
Step-by-step explanation:
Information processing biases are described as the biases that occurs due to illogically or irrationally processing information. Self-serving bias is described as the investigating information and pursuing it to promote their self-interest that leads to a bias as it may encourage unethical or irrational decisions that could be unfavorable for the others.
In the given situation, Adam's thought process reflects a 'self-serving bias' as he processes the information in his 'self-interest' as he thinks 'his marriage failed because he and his wife were poorly matched'. This statement could be irrational as it would affect his ex-wife emotions because he doesn't offer a logical or ethical reason for breaking his alliance. Thus, option A 'self-serving bias' is the answer.
