Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 4.315\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=c1cc(C(F)(F)F)[nH]c2c(OC(F)(F)F)cccc12
b.) COc1ccc(NC(=O)c2nc[nH]c2C(=O)N2CCN(C(=O)OC(C)(C)C)CC2)cc1
c.) Cc1ccc2nc3c(cc(C(=O)NCCCn4ccnc4)n3C)c(=O)n2c1
d.) CN(C)CCCNCCCNC(=O)/C=N/O
Answer: a. O=c1cc(C(F)(F)F)[nH]c2c(OC(F)(F)F)cccc12
