Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.840\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:

(b) O=c1c2cc(Cl)ccc2nc(-c2ccc(Cl)c(Cl)c2)n1O
(c) Cc1ccc(S(=O)(=O)N2CCN=C2c2ccccc2)cc1C
(d) CC(C)(C)C(=O)CN1CCN(C2c3ccccc3-c3ccccc32)CC1
Answer: a. COCCn1c(C)cc(C(=O)COc2cccnc2[N+](=O)[O-])c1C
