Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 6.989\% 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, or d without using any additional words.
Options:
a. COc1ccc(/C=C2\N=C(SC)N(c3ccccc3OC)C2=O)cc1
b. C/C(N)=C(/C#N)C(=O)COC(=O)COc1ccc(Cl)cc1C
c. CC(=O)NC(CCS(C)(=O)=O)C(=O)Nc1cc(C)ccc1C
d. CCOc1ccc(OCC)c(NC(=O)CN(c2ccc(C)cc2)S(=O)(=O)c2c(C)noc2C)c1
Answer: c. CC(=O)NC(CCS(C)(=O)=O)C(=O)Nc1cc(C)ccc1C
