Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.774\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a Cc1ccccc1NC(=O)C(Cc1ccccc1)n1cccc1
b O=C(N/N=C/C=C/c1ccccc1)c1cc2c(ccc3ccccc32)o1
c O=C(Nc1ccncc1)c1cccc(F)c1
Answer: c. O=C(Nc1ccncc1)c1cccc(F)c1
