The answer is secretory vessicles. They transport the modified proteins and lipids from the Golgi apparatus to the outside of the cells. They are especially abundant in secretory cells. They bud from the trans side of the Golgi apparatus. Golgi apparatus are flattened disks of the membrane with cisternae. They transport, fold and modify proteins and lipids in a cell. The cis side of Golgi apparatus is located in close proximity to the endoplasmic reticulum that manufactures the proteins and lipids.

Hope this help
I'm pretty sure it would be D, since
There are two known gene products, RNA and protein.
The regulation of gene expression is important because in different moments of human deveopment different substances are needed and also during the stable fase of human development (adulthood) necessities are dieverse.
The regulation of gene expression is what makes cells and an tissues different and that is why it's also so important.
This question is indeed not east. Hope I suplied enough information according to your needs (there is still way more info on the subject).
Hope it helped,
Happy homework/ study/ exam!
