Task: Answer the multiple choice question.
Question: Which drug has a 2.062\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(c1cccc(C(F)(F)F)c1)C1CCCN(Cc2cccn2-c2ncccn2)C1
b: CCNC(=S)N/N=C(\C)c1cccc([N+](=O)[O-])c1
c: O=C(C1CCCN(Cc2nc(-c3ccc(Cl)cc3)no2)C1)N1CCOCC1
Answer: b. CCNC(=S)N/N=C(\C)c1cccc([N+](=O)[O-])c1
