C. The Jews knew about the valuable technology and had widespread financial connections is the correct answer.

Explanation:

A decree was issued by Spanish royal family on 31 March 1492, it declared that all the Jews who refuse to become Christians will have to leave the country.  Most of the Jews chose exile  and moved to the part of North Africa, Americas and Nether lands.  They brought the printing press but it was not put to widespread use, they used their connections, skills and capital and commercial relation to establish themselves in their new home. They contributed in craft production and other professions.
