Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.239\% 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, or d without using any other words.
Options:
(a) C=CCn1cnc2c(c1=O)c1nc3ccccc3nc1n2/N=C/c1cccc(OC)c1OC
(b) O=c1[nH]c(N2CCCCC2)nc2ncn(Cc3ccccc3)c12
(c) c1ccc(C[C@H]2CN=C(Nc3ccccc3)N2CCC2CCCC2)cc1
(d) CN(CC1CCCO1)S(=O)(=O)c1ccc(C(=O)Nc2ccc(S(N)(=O)=O)cc2)cc1
Answer: b. O=c1[nH]c(N2CCCCC2)nc2ncn(Cc3ccccc3)c12
