Task: Answer the multiple-choice question.
Question: Which drug has a -17.738% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(NCCCn1ccnc1)c1ccc2ccccc2c1
(b) O=C(CSc1ccc(Cl)cc1)NC1CCCC1
(c) OC1C[N+]2(CCCCC2)C1.[Cl-]
(d) Cl.O=C(NCCCN1CCOCC1)c1coc2ccccc2c1=O
(e) O=[N+]([O-])c1ccc(S(=O)(=O)N2CCN(c3ccnc4cc(Cl)ccc34)CC2)cc1
Answer: a. O=C(NCCCn1ccnc1)c1ccc2ccccc2c1
