Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -11.549\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. CCn1cc(CNC(=O)CSc2nc(-c3ccc(OC)c(OC)c3)cc(C(F)(F)F)n2)c(C)n1
b. C=C(C)CC(NCc1ccco1)c1ccc(OC)cc1
c. COc1cccc(OCc2cc(/C=N/n3cncn3)ccc2OC)c1
d. COc1ccc2ccc(=O)oc2c1C(=O)C=C(C)C
e. CCC1(C)Cc2ccccc2-c2nc(NCCCO)n(-c3ccccc3)c(=O)c21
Answer: d. COc1ccc2ccc(=O)oc2c1C(=O)C=C(C)C
