Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.218\% 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) COc1cccc(C(CNC(=O)C(c2ccccc2)c2ccccc2)N(C)C)c1
b) CCn1nnnc1SCC(=O)c1ccc(NC(C)=O)cc1
c) CCSc1cc(N2CCCC2)nc(-c2ccccc2)n1
d) O=C(CCC1CCCNC1)c1ccccc1
Answer: c. CCSc1cc(N2CCCC2)nc(-c2ccccc2)n1
