Problem statement: Answer the multiple-choice question.
Query: Which drug has a 5.776% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN=C1S/C(=C\c2cccn2-c2cccc(Br)c2)C(=O)N1C
b C=CCN(C(=O)Cc1cccs1)c1nc(-c2ccc(S(C)(=O)=O)cc2)cs1
c N#CCCN1CCN(S(=O)(=O)c2ccc(S(=O)(=O)NC3CCCCC3)cc2)CC1
d COCCn1c(C)cc(/C=C2/NC(=O)N(c3cccc(Cl)c3)C2=O)c1C
Answer: a. CN=C1S/C(=C\c2cccn2-c2cccc(Br)c2)C(=O)N1C
