Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.063\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(c1ccco1)N1CCN(c2ncnc3scc(-c4ccccc4)c23)CC1
b. COC(=O)C1=CN(CCCN2CCCC2=O)C=C(C(=O)OC)C1c1cccs1
c. Cc1ccc(NC(=O)CSc2nc3c([nH]c4ccccc43)c(=O)n2C)cc1
d. CS(=O)(=O)N(CC(=O)Nc1ccccc1C(=O)NCCc1ccccc1)c1ccc2c(c1)OCCO2
Answer: a. O=C(c1ccco1)N1CCN(c2ncnc3scc(-c4ccccc4)c23)CC1
