The correct answer is C) American ideas conflict with traditional Iranian ideas.
Leaders in Iran want to limit American cultural infusion because American ideas conflict with traditional Iranian ideas.
Iran is a very conservative country. People from Iran are Muslims, they practice the strict teachings of Islam. They have to follow strict rules on how to pray and how many times they have to pray during the day, they have to fast during the Ramadan, women had to cover their heads and dress conservatively, among many other things. American ideas are more liberal, women are free to do and act as they want, citizens are free to do what they want legally and under the laws of the Constitution. So there are many cultural differences between the two countries.
