Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.758% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(CN1C(=O)CSc2ccccc21)N1CCc2ccccc21
b) CN1CCN(CCCNC(=O)Nc2ccc([N+](=O)[O-])cc2)CC1
c) CC(NC(=S)NCCc1ccccc1)C(c1cccs1)N1CCN(C)CC1
d) Cc1c(C(=O)NCC2CCCO2)oc2c(Cl)cccc12
Answer: a. O=C(CN1C(=O)CSc2ccccc21)N1CCc2ccccc21
