Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.927\% 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(NC1CCCC1)C1CCC(=O)N1CCc1ccccc1
b) O=S(=O)(c1ccccc1)c1nc(-c2ccccc2)oc1N1CCCC1
c) O=C(Cn1nc(-c2ccccc2)nc1-c1ccccc1)OC1CCCCC1
d) COc1ccccc1-n1c(=O)[nH]c2c(C(N)=O)nc(-c3cccnc3)nc21
Answer: d. COc1ccccc1-n1c(=O)[nH]c2c(C(N)=O)nc(-c3cccnc3)nc21
