Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.353\% 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(CCn1cnc2ccccc21)N/N=C/C=C/c1ccccc1
b. O=C(N/C(=C/c1cccnc1)C(=O)N1CCOCC1)c1ccccc1F
c. CN1CCN(C(=O)c2ccccc2Nc2ccc(SC(F)F)cc2)CC1.Cl
d. C/C(=N\NC(=O)c1nc(C)cc(C)n1)c1ccccc1
e. COc1ccc(N(CCC#N)S(=O)(=O)c2ccc(Cl)cc2)cc1
Answer: a. O=C(CCn1cnc2ccccc21)N/N=C/C=C/c1ccccc1
