Answer:
HIV stands for Human Immunodeficiency Virus, as the name says, it's a deficiency of the immune system, which attacks T cells, lymphocytes responsible for central functions of the whole system. A dramatic consequence of HIV is that it doesn't have cure, if you get it, you will have it the entire life.
However, if you take your medicine, you will live a norma life, because having HIV not necessarily means that you will also have AIDS which is Acquired Immune Deficiency Syndrome which is a complete disfunction of the immune system, the last stage oh HIV, ending in death.
Therefore, the correct answer is the first one "there is no cure for HIV". Because other ones are just not true. HIV is a virus not a bacteria. Also, it's not transmitted by a casual contact like hugs, a blood exchange is needed to catch HIV. At last, not all HIV patients develop AIDS, not always happens.
