Task: Answer the multiple choice question.
Query: Which compound has a 2.011\% 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 additional words.
Options:
a CCN(CC)S(=O)(=O)c1ccc(C(=O)OC2CCCCC2CN(C)C)cc1
b O=C(Cn1nc(-c2ccccc2)ccc1=O)NCc1ccc(F)cc1
c O=C(O)c1ccccc1C(=O)Nc1ccc(-n2nccc2C(F)(F)F)cc1
d CCOCCCNC(=O)c1ccccc1SC
e Cc1ccc(-c2cc(C(=O)NC3=NCCS3)c3cc(Br)ccc3n2)o1
Answer: b. O=C(Cn1nc(-c2ccccc2)ccc1=O)NCc1ccc(F)cc1
