Task: Answer the multiple choice question.
Query: Which drug exhibits a -38.295% 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] CSC(=NC#N)N1CCN(c2ccc(Cl)cc2)CC1
[b] CCN(C(=O)COC(=O)c1cc(-c2ccccc2)nc2c1c(C)nn2-c1ccccc1)C1CCS(=O)(=O)C1
[c] COc1ccc(NC(=O)CCN2CCC(C)CC2)cc1
[d] C=CCSc1nc(Cc2ccc(Cl)cc2)nc2ccccc12
Answer: a. CSC(=NC#N)N1CCN(c2ccc(Cl)cc2)CC1
