Barter system- A method of exchange when no money is involved.
B and C can't be the answers because they are not exchanging anything.
D can't be the answer either because there is money involved.
So your answer is A) You trade an apple for a banana at school. because you are exchanging something with someone for something else thats not money.
Hope this Helps!!
The answer is #1 Prohibited Alcohol and #4 Prohibited cannabis and hashish.
Islam is opposed to the use of any drugs except for those which are medically prescribed. According to their Prophet Muhammad - Every intoxicant is Khamr (alcohol) and all Khamr is Haram (unlawful or not permitted). They see alcohol and psychoactive drugs as satanic devices used to sway people away from the word of Allah (God). In Islam followers are allowed to smoke tobacco but do not accept the use of opium unless it is in the form or medically prescribed morphine.
