    Answer : Option A

    Explanation :

    The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas. On Earth, carbon dioxide makes up only a tiny fraction of the atmosphere. However, man-made emissions have caused carbon dioxide concentrations here to increase by about 30% since pre-industrial times.
