Task: Answer the multiple-choice question.
Question: Which drug exhibits a 20.439\% 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 additional words.
Options:
a. COc1cc2c(cc1O)CC[n+]1cc3c(OC)c(OC)ccc3cc1-2
b. Cc1ccc(S(=O)(=O)N2Cc3ccccc3CC2C(=O)Nc2cc(C)on2)cc1
c. C/C(N)=C(/C#N)C(=O)CSc1nnc(-c2ccc3c(c2)OCO3)o1
d. NC(=O)CSc1ncnc2c1oc1ccccc12
Answer: c. C/C(N)=C(/C#N)C(=O)CSc1nnc(-c2ccc3c(c2)OCO3)o1
