The correct answer is
B: Hector Nuñez was a crypto-Jew, a Jew who publicly professed to follow the Christian faith to avoid persecution from the Portuguese Inquisition. He eventually fled Portugal, arriving in England in 1546, where he went on to become a successful merchant, trading in wine, raisins, and other goods. Through his business and family contacts he was able to learn information about the Spanish Armada preparations to launch their assault, which he passed on to the English, giving them forewarning of the Armada’s position and plan of attack. This spying effort was instrumental in enabling England to successfully ward off the invasion.
