Sean Is Having a Conversation with a Friend, Making Fun

Sean is having a conversation with a friend, making fun of how foolish spammers are. Clearly, he says "These emails are just sent by the millions and look like it. Only an idiot falls for them." In the meanwhile Sean is reading an email addressed to him. It says:
---
Dear Sean,
I understand you did some work awhile back for an orfanage in Brazil. Sorry to bother you sir, we have never meet, but I am a 13 year old boy whose parents were taken the the states. I need some money to get them to reurn safely or if I can greet them there in the states too. Can you help?

Sean remembers his trip to Brazil and thinks of a boy he met there (He met hundreds, but the mind plays tricks like this on the best of us) . He wonders for a moment if this might be him.
What technique is Sean about to fall prey too?

A) SPAM & Scam Sandwich
B) Brazilian Spam Squad
C) Spear Phishing
D) South American 419 Scam
