Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.695\% 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, c, or d without using any other words.
Options:
a) CC1CC(C)(C)NC(=S)N1CCC(=O)Nc1ccc2c(c1)OCCO2
b) CCCOc1ccc(/C(CC)=N/NC(=O)C2(C)CC2(Br)Br)cc1
c) CCOc1ccccc1NC1=CC(=O)CC(c2ccccc2)C1
d) Cc1[nH]c2ccccc2c1CC#N
Answer: d. Cc1[nH]c2ccccc2c1CC#N
