Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.546\% 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 additional words.
Options:
a Cc1ccc(C2Nc3ccccc3-c3nc4ccccc4n32)o1
b COC(=O)CSc1nc2ccc(NC(C)=O)cc2s1
c N#CCSc1nc2c(c(=O)n1Cc1ccccc1)C1(CCCC1)Cc1ccccc1-2
d Cc1cc(C)c2cc3c(N)c(C(=O)Nc4c(C)[nH]c(=O)[nH]c4=O)sc3nc2c1
Answer: c. N#CCSc1nc2c(c(=O)n1Cc1ccccc1)C1(CCCC1)Cc1ccccc1-2
