Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.340\% 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 other words.
Options:
a: Cc1cccc(Oc2ncnc(N)c2[N+](=O)[O-])c1C
b: O=C(O)CCc1nc2cc(C(F)(F)F)ccc2n(Cc2ccccc2)c1=O
c: Nc1nc(Nc2ccccc2F)nc(NCCO)c1[N+](=O)[O-]
Answer: a. Cc1cccc(Oc2ncnc(N)c2[N+](=O)[O-])c1C
