Sapphire Mining in Northern Madagascar Takes Place in the Territory

Sapphire mining in northern Madagascar takes place in the territory of the Ambondromifehy.The Ambondromifehy doubt that sapphires are used as jewellery and speculate that they are used in the making of electronics,military vehicles,and even bombs.This seems to be a strange understanding;what is the best explanation offered by anthropologists?

A) Some people still do not have access to completely accurate information sources but this will change with the spread of the Internet.
B) The Ambondromifehy believe this because they were informed by outsiders that sapphires are used for other purposes.
C) All people must use existing beliefs and world views to speculate about things that are sometimes unknowable.
D) Everyone has mistaken beliefs that are nonsensical,but we should not judge other cultures without considering our own situation.
