Task: Answer the multiple choice question.
Question: Which drug has a 2.947\% 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, c, d, or e without using any additional words.
Options:
a. O=C(CCc1nnc(CCCCc2ccccc2)o1)N(CCO)Cc1ccccc1
b. C=CCC(CC=C)(C(=O)O)c1ccccc1
c. CCOC(=O)C(CC)n1cnc2sc3c(c2c1=O)CCC3
d. O=C1C2C3C=CC(C3)C2C(=O)N1Cc1ccccc1
e. O=Cc1cccc(Oc2ccc([N+](=O)[O-])cc2[N+](=O)[O-])c1
Answer: b. C=CCC(CC=C)(C(=O)O)c1ccccc1
