Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.730\% 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) O=C(Nc1nccs1)C(NS(=O)(=O)c1ccc(Br)s1)c1ccccc1
(b) COc1ccc(OC)c(-c2cc(C(=O)Nc3c(C)nn(Cc4ccccc4)c3C)no2)c1
(c) CN1CCN(c2ccccc2NC(=O)c2cc3ccccc3o2)CC1
(d) O=C(NC1CCCC1)C(c1cccs1)N(CC1CCCO1)C(=O)Cc1cccs1
Answer: d. O=C(NC1CCCC1)C(c1cccs1)N(CC1CCCO1)C(=O)Cc1cccs1
