Problem statement: Answer the multiple choice question.
Question: Which drug has a -2.597\% 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(CCCN1C(=O)CCC1=O)Nc1ccc(Br)cc1F
b CCOC(=O)c1c(C)[nH]c(C(=O)OCC(=O)Nc2cc(C)c(Cl)cc2OC)c1C
c O=C(N/C(=C\c1ccc(Br)cc1)C(=O)N1CCCC1)c1ccccc1F
d CCCc1nnc(SCC(=O)Nc2ccc(OC)cc2)n1N
Answer: a. O=C(CCCN1C(=O)CCC1=O)Nc1ccc(Br)cc1F
