They are the SAME structure, in different organisms, connected through evolution.
A common example are the arms of humans, the wings of a bat, the fins of a whale, are all the same bones but have been adapted for different uses.

what is Similar structures that related species have inherited from a common ancestor
True. The more distantly related two organisms are in evolutionary terms, the fewer homologous structures they are likely to share. Homologous structures are features that have a common evolutionary origin, so closely related organisms are expected to have more similarities in their structures compared to more distantly related organisms.
I learned about homologous and heterozygous structures in Biology.
They don't, Homologous structures, such as the bones in your forearms and the bones in your cat's and dog's forelegs are that similar because you and your pets are mammals and closely related on the evolutionary tree. Before modern genetic showed this to be convincing the study of morphology was showing us pretty much the same thing; homologous structures support evolution.
homologous structures (correct answer, your response)
Some structures that related species have inherited from a common ancestor are homologous structures, which are similar in form and function but may have different appearances due to adaptations to different environments. Another example is vestigial structures, which are remnants of structures that were functional in ancestral species but have reduced or lost their original function in descendants. Analogous structures are also seen in related species, having similar functions but different origins, such as the wings of birds and insects.
