Task: Answer the multiple choice question.
Question: Which drug exhibits a -7.733\% 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 additional words.
Options:
a O=C(c1cccnc1)N(Cc1ccccc1)c1ccccc1
b O=C(COC(=O)c1cccnc1)Nc1ccc(F)cc1
c Cl.OC1(c2ccccc2)CNCCc2ccccc21
d O=C(CN1CCC(O)(c2cccc(F)c2)CC1)NCCc1c[nH]c2ccccc12
Answer: a. O=C(c1cccnc1)N(Cc1ccccc1)c1ccccc1
