Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.273\% 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 other words.
Options:
a. COc1ccc(-n2c(=S)[nH]c3cc(C(=O)NCCCN4CCCC4=O)ccc3c2=O)cc1OC
b. COc1ccc(-n2cccc2/C=C2/NC(=O)N(c3cccc(Cl)c3)C2=O)cc1
c. CN1CCN(C(=O)C23CC4CC(CC(C4)C2)C3)CC1
d. CCn1c(SCC(=O)c2[nH]c(C)c(C(C)=O)c2C)nnc1-c1cccs1
Answer: a. COc1ccc(-n2c(=S)[nH]c3cc(C(=O)NCCCN4CCCC4=O)ccc3c2=O)cc1OC
