Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.503% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1cccc(/C=N/NC(=O)CSCC(=O)Nc2ccccc2)c1O
(b) CC1(C)SC(=S)N(/N=C/c2ccccc2)C1N(O)C(=O)Nc1ccc([N+](=O)[O-])cc1
(c) C1CCCCC1.OCCN1CCN(C2Cc3cc(Cl)ccc3Sc3ccc(Cl)cc32)CC1
(d) COc1ccc(NC(=O)[C@H](C)NC(N)=O)cc1S(=O)(=O)Nc1cc(C)ccc1Br
Answer: a. COc1cccc(/C=N/NC(=O)CSCC(=O)Nc2ccccc2)c1O
