Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.022\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(CNC(=O)c1ccccc1Br)N/N=C/c1ccc(O)cc1
b) N#Cc1c(N)nc2c(c1-c1ccncc1)CCCCCC2
c) O=C(OCCOc1ccccc1Cl)c1ccc(-n2cnnn2)cc1
Answer: a. O=C(CNC(=O)c1ccccc1Br)N/N=C/c1ccc(O)cc1
