Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.988\% human ether-à-go-go related gene (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=C(CSc1nnc(-c2cccnc2)n1Cc1ccco1)c1ccccc1
b) O=C(N/N=C/c1ccc(C(F)(F)F)cc1)c1ccncc1
c) Cc1nc(C(=O)NC2CCOCC2)sc1C1(C)CC(c2cccc([N+](=O)[O-])c2)=NO1
d) Fc1ccc(-c2nnc(NC3=NCCCCC3)o2)cc1
Answer: b. O=C(N/N=C/c1ccc(C(F)(F)F)cc1)c1ccncc1
