Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.174\% 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 other words.
Options:
a Cc1ccc(S(=O)(=O)Oc2ccc(C3C4=C(CCCC4=O)OC4=C3C(=O)CCC4)cc2)cc1
b CCOC(=O)c1c(-c2ccc(C)cc2)csc1/N=C/N(C)C
c Cc1ccc(/C=C2/C(=O)NC(=O)N(Cc3ccc(F)cc3)C2=O)o1
d Cc1cccn2c(=O)c3cc(C(=O)NC4CCCCC4)n(C)c3nc12
e CSCCC(NC(=O)c1ccc(Cl)cc1Cl)C(=O)NNC(=O)c1ccncc1
Answer: b. CCOC(=O)c1c(-c2ccc(C)cc2)csc1/N=C/N(C)C
