"Carpeting", and "furniture increased ventilation" inefficient indoor cook stoves "VOCs from paints".

Option: C

Explanation:

VOC's are really harmful solvents that are released in the air as the paint dries. The VOC's can create acute health symptoms which may result harmful after some time, like dizziness, headache, and many more. Generally, the long term effects are not that evident, but some VOC's are more carcinogens according to US environmental protection agency. Although, many paint companies claim that their paints are VOC free which is actually false. It might be true that the VOC is not present in the base of the paint, but when the pigment is added to the paint the VOC increases. Hence, carpeting, furniture, cook stoves and VOC's from paints are really harmful indoor pollutants.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
