Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.655\% 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) Cn1c(=O)oc2cc(S(=O)(=O)N3CCC(C(=O)NCCc4ccccc4)CC3)ccc21
b) COc1ccc(NC(=O)Cc2c(Sc3ccccc3)c3ccccc3n2C)cc1
c) COc1ccccc1NC(=O)CSC1=NC(=O)C(Cc2ccccc2)C(=O)N1
d) CCOC(=O)c1ccc(NS(=O)(=O)c2cn(C)cn2)cc1
Answer: c. COc1ccccc1NC(=O)CSC1=NC(=O)C(Cc2ccccc2)C(=O)N1
