Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.963% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COc1ccccc1/C=C/c1nc2ccc(OC(C)=O)cc2c(=O)o1
(b) O=C(O)c1cccc2c1/C(=N/Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-])c1ccccc1-2
(c) CCCCn1c(O)c(C=Nc2c(C)n(C)n(-c3ccccc3)c2=O)c(=O)[nH]c1=O
(d) Cc1ccc(C2C=C(c3ccccc3)Nc3ncnn32)cc1
(e) Cc1c(C(=O)NC2=NCCS2)cccc1[N+](=O)[O-]
Answer: c. CCCCn1c(O)c(C=Nc2c(C)n(C)n(-c3ccccc3)c2=O)c(=O)[nH]c1=O
