Homogeneous solution will be formed by 
Further Explanation:
Homogeneous solution consists of only one phase. It is formed when the substances are completely dissolved in each other. Solubility is the property of any substance that makes it soluble in other substances. It is governed by the principle “like dissolves like”.
a.
and 
Both are non-polar hydrocarbons and completely dissolve in each other. So a homogeneous solution is formed by
and
.
b. LiBr and 
LiBr is an ionic compound whereas
is a non-polar hydrocarbon. Both will not dissolve in each other. So homogeneous solution will not be formed by LiBr and
.
c.
and 
is a symmetric molecule and non-polar in nature whereas
is a polar molecule. Both will not dissolve in each other. So homogeneous solution will not be formed by
and
.
d.
and
is a non-polar hydrocarbon whereas
is a polar molecule. Both will not dissolve in each other. So homogeneous solution will not be formed by
and
.
