Task: Answer the multiple choice question.
Question: Which drug has a 9.634\% 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: CNS(=O)(=O)c1cccc(C(=O)OCc2cc(=O)n3cc(Br)ccc3n2)c1
b: Cl.O=C(O)CSc1nc(-c2ccccc2)c(-c2ccccc2)[nH]1
c: CCN(c1cccc(C)c1)S(=O)(=O)c1ccc2c(c1)oc(=O)n2C
d: N#Cc1c(C(F)(F)F)cc(C2CC2)nc1N1CCCC1
e: Cc1cc(SCC(=O)OCC(=O)NCC2CCCO2)c(C)cc1Br
Answer: b. Cl.O=C(O)CSc1nc(-c2ccccc2)c(-c2ccccc2)[nH]1
