Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.748\% 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=c1[nH]c(CSc2ncn[nH]2)nc2ccccc12
b) O=C(Nc1cc(C(=O)N2CCOCC2)cc(C(=O)N2CCOCC2)c1)c1cc(F)c(F)cc1Cl
c) CCCC(=O)c1c[nH]c(C(=O)NCCCN2CCOCC2)c1
d) CS(=O)(=O)N1CCN(C(=O)c2ccncc2)CC1
e) O=C(Nc1nnc(SCC(=O)N2CCCCC2)s1)C1CCCCC1
Answer: d. CS(=O)(=O)N1CCN(C(=O)c2ccncc2)CC1
