Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.705\% 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(CSc1ccc2nnc(-c3ccccc3)n2n1)N1CCCc2ccccc21
b.) CCN1CCN(c2c(/C=C3\SC(=S)N(Cc4ccco4)C3=O)c(C)c(C#N)c(=O)n2C)CC1
c.) Cc1ccc(-c2n[nH]c(=S)n2/N=C/c2ccc(C)s2)cc1
d.) Cc1cc(C)c(NC(=O)C2CCCN2C(=O)NC2CCCCC2)c(C)c1
Answer: b. CCN1CCN(c2c(/C=C3\SC(=S)N(Cc4ccco4)C3=O)c(C)c(C#N)c(=O)n2C)CC1
