Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.875\% 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. N#Cc1cc(C(=O)c2cc(Cl)ccc2O)cn(-c2ccccc2)c1=O
b. O=C1Nc2ccc(C(F)(F)F)cc2N2CCCC12
c. COc1ccccc1CN1CC(C(=O)NCCSc2nnnn2C)CCC1=O
d. O=C(c1ccco1)N1CCN(S(=O)(=O)c2cc(Cl)ccc2Cl)CC1
Answer: d. O=C(c1ccco1)N1CCN(S(=O)(=O)c2cc(Cl)ccc2Cl)CC1
