Love & Lust and how they are fickle because after one meeting they fall desperately in love
The third option is correct: "Art and math are courses architecture students must have on their schedules."
The other two uses the word "their" when referring to a single thing/person. The correct word should be: "Each architecture student must plan his/her high school and college courses carefully." and "Every school of architecture sets its own specific requirements."
In my opinion i think it's the answer is B a dictionary???
