Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.460\% 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 other words.
Options:
a) Cc1ccsc1/C=N/NC(=O)c1ccc2ccccc2c1
b) O=C(Cn1c(NCCO)nc2ccccc21)NCC1CCCO1
c) O=C(c1cccc(NS(=O)(=O)c2ccc(F)c(F)c2)c1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
d) COc1ccccc1N(CC(=O)Nc1cc(C)on1)S(=O)(=O)c1ccc(Cl)cc1
Answer: c. O=C(c1cccc(NS(=O)(=O)c2ccc(F)c(F)c2)c1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
