Task: Answer the multiple-choice question.
Question: Which drug exhibits a 19.311% 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: CC(C)C[C@@H]1NC(=O)[C@H](Cc2ccccc2)N(C)C(=O)[C@H](C)NC(=O)c2ccccc2NC(=O)[C@H](Cc2ccc(O)cc2)N(C)C1=O
b: CCn1nc(C)c(CCC(=O)O)c1C
c: COc1ccc(-c2cc(C(F)(F)F)n3ncc(C(=O)Nc4c(C)n(C)n(-c5ccccc5)c4=O)c3n2)cc1
d: CCCNC(=O)c1[nH]c(C)c(C(C)=O)c1C
Answer: d. CCCNC(=O)c1[nH]c(C)c(C(C)=O)c1C
