Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.012\% human ether-à-go-go related gene (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.) CNS(=O)(=O)c1ccc(NC(=O)C(CCSC)NC(N)=O)cc1
b.) COC(=O)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)[C@@]2(C)NC(=O)c2ccccc2)[C@H](c2ccccc2)n2c(=O)n(-c4ccccc4)c(=O)n2[C@@H]3C1
c.) C=CCn1c(SCC(=O)c2ccc(OC)cc2)nnc1-c1cc2cccc(OC)c2o1
d.) COc1ccc(NC2CCCN(C(=O)c3csc(C(C)C)n3)C2)cc1
Answer: b. COC(=O)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)[C@@]2(C)NC(=O)c2ccccc2)[C@H](c2ccccc2)n2c(=O)n(-c4ccccc4)c(=O)n2[C@@H]3C1
