Task: Answer the MCQ question.
Query: Which drug has a 6.370% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCOC(=O)C1=C(CC)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
b. Cc1ccc(CSc2ccc(C(=O)N3CCOCC3)cc2[N+](=O)[O-])cc1
c. COCCOC(=O)c1c(C)oc2ccc(NS(=O)(=O)c3ccc(C)cc3)cc12
d. COc1ccc(-c2[nH]ncc2CN2CCC(c3ccncc3)CC2)cc1F
Answer: a. CCOC(=O)C1=C(CC)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
