Task: Answer the multiple choice question.
Query: Which drug has a 4.406\% 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: CCN1CCN(c2c(Cl)cccc2NC(=O)c2cc3ccccc3o2)CC1
b: CC(C)(C)OC(=O)[C@H](Cc1ccccc1)NC(=O)c1[nH]cnc1C(=O)Nc1cccc(Cl)c1
c: O=C(NCc1ccccc1F)c1cccc(S(=O)(=O)N2CCCCCC2)c1
d: O=C(NCc1cccnc1)c1cccc(-c2cc3ccccc3oc2=O)c1
Answer: a. CCN1CCN(c2c(Cl)cccc2NC(=O)c2cc3ccccc3o2)CC1
