A.) I didn't know how to get home; as a result, I got lost.

When using a semicolon, there should be an independent clause on both sides; it has the same function as a comma and a coordinating conjunction (FANBOY). For example, "I didn't know how to get home; as a result, I got lost" could be replaced with, "I didn't know how to get home, so as a result, I got lost."
