Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.448\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cc1cnc(NC(=O)c2c(-c3ccccc3)noc2C)s1
b CC(=O)N1CCN2C(=O)C1CCCC(=O)c1cc(C)ccc12
c COc1ccc(C(=O)NCc2ccc(-c3nc4ccccc4s3)cc2)cc1OC
d CC(C)CSc1nc2c(c(=O)[nH]c(=O)n2C)n1CCc1ccccc1
e O=C(c1cccs1)N1CCN(c2ncc(Br)cn2)CC1
Answer: e. O=C(c1cccs1)N1CCN(c2ncc(Br)cn2)CC1
