Task: Answer the multiple choice question.
Query: Which compound has a 4.005\% 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.) CCCSc1nc(N)nc(-c2cccs2)c1C#N
b.) Cc1nc(-c2cccc(Br)c2)ccc1C(=O)O
c.) CC(=O)N1c2c(cc(Br)cc2S(=O)(=O)NCc2cccnc2)CC1C
d.) O=C(CCN1C(=O)/C(=C/c2cccs2)SC1=S)N1CCCCC1
Answer: a. CCCSc1nc(N)nc(-c2cccs2)c1C#N
