Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.983\% 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, or c without using any other words.
Options:
[a] CCOc1cccc2c1OC1(CCCCC1)N1N=C(c3cccnc3)CC21
[b] CC(Oc1ccc2c3c(c(=O)oc2c1)CCCC3)C(=O)N[C@@H](Cc1ccccc1)C(=O)O
[c] CC1(C)CN(c2ccc(C(=O)c3ccccc3)cc2)C1=O
Answer: a. CCOc1cccc2c1OC1(CCCCC1)N1N=C(c3cccnc3)CC21
