Answer: Family, Social and Neglect
Explanation:
Family Risk Factors: Family risk factors include childhood maltreatment in which the parent child relationship, marital status of parents, level of understanding among the family members also influences the abuse of alcohol and drug abuse.
Social Risk Factors: The society in which the person or child is living also influences the drug, tobacco and alcohol abuse. A teenage easily gets influenced by the society and place where they are living.

The right answer is A.) DNA in mitochondria
.
Eukaryotic cells, with their many intracellular organelles, have long been considered progeny of prokaryotes that would have become more complex as a result of genetic mutations. But from the 1960s, biologist Lynn Margulis proposed an alternative explanation that was first received coldly by the scientific community. His endosymbiotic theory, proposed in a more formal way in a 1981 book, proposes that eukaryotic cells as we know them today would be the result of a series of symbiotic associations with different prokaryotes.
Mitochondria and chloroplasts also have their own DNA that is not trapped in a nucleus, which is also the case with prokaryotes. However, the proteins encoded by this DNA do not cover all mitochondrial proteins. The prokaryote is thought to have lost some genes to the nucleus of the cell, a process known as "endosymbiotic gene transfer". For this reason, mitochondria and chloroplasts are now host-dependent for the synthesis of most of their components.
A) both have strong scientific support.
