The islamic golden age is characterized by which of the following achievements?
a. the forced conversion of christians to islam
b. many important advances in science and medicine
c. islam’s spread throughout western europe
d. the end of strict enforcement of sharia law

A. is out
B . While B is true it was general that they made important advances, it wasnt something new

We are left with C and D.
D is out... its not really an achievement that contributed to the Golden Age.
You see,the Golden age had to do with other nations and the spread of culture and religion of Islam as well as trade.

SO the answer is C. Islam spread through Western Europe which led to the blending of cultures  and helped promote trade.

Hope this helped!
