Task: Answer the multiple-choice question.
Query: Which drug exhibits a 23.373\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COCCNC(=O)CSc1ncnc2sccc12
b CCOC(=O)c1cnn(CCOC(=O)c2ccc(OC)cc2)c1NC(=O)c1ccc(OC)cc1
c CCOc1ccc(NC(=O)CN(C)C(=O)/C=C/c2ccco2)cc1OCC
d CCOC(=O)CSc1nnc2c3ccccc3n(C)c2n1
e O=C(CSCC(=O)Nc1nc(-c2ccc3c(c2)OCO3)cs1)Nc1nccs1
Answer: a. COCCNC(=O)CSc1ncnc2sccc12
