Task: Answer the multiple-choice question.
Question: Which drug has a 1.769\% 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 other words.
Options:
(a) O=C(NCCc1ccccc1)c1nnc(CS(=O)(=O)c2ccccc2)o1
(b) Cc1cc(N(CCCl)CCCl)ccc1/C=N/NC(=O)c1ccco1
(c) COC(=O)CSc1nnc(CNC(=O)Cc2ccccc2)n1-c1ccccc1OC
(d) O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1ccc(Br)cc1
Answer: c. COC(=O)CSc1nnc(CNC(=O)Cc2ccccc2)n1-c1ccccc1OC
