Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.418\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C1Oc2ccccc2C(=O)/C1=C\N1CCN(c2ccccc2)CC1
b. COc1ccc(C2C(C(=O)N3CCCC3)CC(=O)N2c2ccc(OC)cc2)cc1
c. Cc1ccc(Nc2nc(-c3sc(NC(=O)c4ccccc4)nc3C)cs2)cc1
Answer: a. O=C1Oc2ccccc2C(=O)/C1=C\N1CCN(c2ccccc2)CC1
