Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.629\% 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 COc1ccccc1-c1nnc(SC2CCc3ccccc3NC2=O)s1
b Cc1noc(C)c1S(=O)(=O)N(CC(=O)N1CCCC1)c1ccc(C(C)C)cc1
c O=C(Cn1cnc(S(=O)(=O)N2CCCC2)c1)Nc1ccc(OC(F)(F)F)cc1
d O=C(Nc1ccnc(-c2ccncc2)n1)c1ccc(Cl)cc1
Answer: d. O=C(Nc1ccnc(-c2ccncc2)n1)c1ccc(Cl)cc1
