Task: Answer the MCQ question.
Question: Which drug exhibits a 13.424\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCC/C(O)=C1\C(=O)CCCC1=NCCc1c(C)[nH]c2ccc(OC)cc12
b. C1=CCC(CN2CCN(C3CCCCCC3)CC2)CC1.O=C(O)C(=O)O
c. COc1ccc(/C=C(/NC(=O)c2ccccc2)C(=O)N/N=C/c2ccncc2)cc1
d. CC(=O)c1cccc(NC2c3ccccc3C(=O)N2Cc2ccc3c(c2)OCO3)c1
Answer: a. CCC/C(O)=C1\C(=O)CCCC1=NCCc1c(C)[nH]c2ccc(OC)cc12
