At the time of organogenesis genes regulate the process at different levels and at different times due to :During development (organogenesis), different genes are switched on and off in different cells and at different times.
In eukaryotes, the coding sequences (exons) of a gene can be joined in different combinations by alternative splicing, so one gene can give different proteins in different tissues and at different stages.
As per the answer key, this regulation at different levels and times is attributed to exons.
(This answer is debatable: control of when and where genes are expressed is usually attributed to promoters and regulatory sequences.)
So, as per the answer key, the answer is exon.
