Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.074\% 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.) O=c1c2cccnc2n(-c2ccccc2)n1Cc1c(Cl)cccc1Cl
b.) CC#CCN1c2ccccc2[C@]23C[C@@H](C(=O)OC)N(C(=O)OCC)C2=NC(C(=O)OC)=C(C(=O)OC)[C@H]13
c.) CCOC(=O)C1CCN(Cc2cnc(Oc3ccc(OC)cc3)s2)CC1
d.) NC(=O)C1CCN(C(=O)CSc2nc3ccccc3s2)CC1
e.) Cc1ccc(S(=O)(=O)O/N=C2/CCCc3occc32)cc1
Answer: a. O=c1c2cccnc2n(-c2ccccc2)n1Cc1c(Cl)cccc1Cl
