Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.740\% 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, c, d, or e without using any additional words.
Options:
(a) O=C(c1ccccc1)N(C1=NCCCCS1)c1ccccc1
(b) Cc1ccc([N+](=O)[O-])c(OCCN2CCNCC2)c1.O=C(O)C(=O)O
(c) O=c1oc2ccc(Br)cc2cc1-c1nc2ccccc2o1
(d) Cc1ccc(NC(=S)N2CCN(C3CCCCC3)CC2)cc1
(e) CCC(C(=O)NCc1ccncc1)c1ccccc1
Answer: b. Cc1ccc([N+](=O)[O-])c(OCCN2CCNCC2)c1.O=C(O)C(=O)O
