Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.239% human ether-à-go-go related gene (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: COC(=O)c1cccc(NC(=O)CC2C(=O)NCCN2C(=O)Nc2ccccc2)c1
b: Cc1cccc(OCc2nnc(N)s2)c1C
c: CC(=O)c1cccc(NC(=O)CN2CCc3cc4c(cc3C2C)OCCCO4)c1
d: CCCc1ncc(C(O)c2cccc(OC)c2)n1C
Answer: a. COC(=O)c1cccc(NC(=O)CC2C(=O)NCCN2C(=O)Nc2ccccc2)c1
