Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.011\% 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, d, or e without using any other words.
Options:
a.) O=C(Nc1ccc2oc(=O)ccc2c1)c1cccnc1
b.) CC1(C)C=C(c2ccc(C(=O)O)s2)CC(C)(C)N1.Cl
c.) CCCS(=O)(=O)N1CCCC(C(=O)Oc2ccc(C)c(C)c2)C1
d.) COCCNC(=O)CCCn1c(=O)c2ccccc2n(Cc2ccccc2C#N)c1=O
e.) COC(=O)N/N=C1/C/C(=N\NC(=O)OC)c2ccccc21
Answer: a. O=C(Nc1ccc2oc(=O)ccc2c1)c1cccnc1
