Problem statement: Answer the multiple-choice question.
Query: Which compound has a 1.787\% 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, or d without using any additional words.
Options:
a. O=C(CSC1=Nc2ccccc2C2=NC(CC(=O)NCc3ccco3)C(=O)N12)NCc1ccco1
b. C=CCNC(=O)CCCc1ccccc1
c. O=C1Nc2ccccc2/C1=C/c1cnc[nH]1
d. CC(/C=N/NC(=O)c1cc(-c2cccs2)[nH]n1)=C\c1ccccc1
Answer: b. C=CCNC(=O)CCCc1ccccc1
