Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.146% 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 additional words.
Options:
(a) CCOc1ccccc1NC(=O)c1cccnc1
(b) COc1cc(C(=O)O)ccc1OC(C)=O
(c) O=C1S/C(=C/c2ccc(N3CCOCC3)o2)C(=O)N1Cc1c(F)cccc1Cl
(d) COc1ccc(NC(=O)c2cccc(S(=O)(=O)N(C)c3ccccc3)c2)cn1
Answer: a. CCOc1ccccc1NC(=O)c1cccnc1
