   B. Develop emotional problems

Explanation:  According to scientific research, quarrels between parents can cause serious emotional problems for children. Not only does it affect young children, but according to scientists, it can also affect young people up to 19 years of age emotionally. Parental quarrels can affect a child's emotional state to the level of a mental emotional disorder. Frequent quarrels of parents also affect the parents themselves, who transmit such energy to their children and children absorb negative energy and stress as something common, and unfortunately it becomes a normal environment and family atmosphere, which is how children's emotions are formed and developed. Children so emotionally affected can show emotional instability on several levels, from insecurity to fear and worry when there is no real need for it, to the lack of a healthy family atmosphere. Of course, emotional problems are the beginning of problems that can develop into other disorders from cognitive to eating problems and creating healthy normal relationships with peers. In the extreme, they can be reflected even in physical health, as well as many other consequences such as the withdrawal and fleeing in psychoactive substances, deviant behaviours that occur in adolescence and later.
