Answer:
b) A series of stars that form a figure
Explanation:
In astronomy, <em>a constellation is any of certain groupings of stars that form an imaginary outline or pattern on the celestial sphere. </em>They are useful to track artificial satellites and in assisting astronomers and navigators to locate certain stars, therefore constellation is a series of stars that form a figure. A constellation can't be a region of the celestial sphere and all of the stars in it because not all stars in the celestial sphere form figures.
They are no figures in the night sky because constellations are starts, therefore they are present during day or night, it's not a term applicable to astrology because this is a pseudoscience not based on facts, like astronomy.

Answer:
Caves, caverns, sinkholes, funnel-shaped holes, underground rivers and lakes
Explanation:
The karst topography is found at places that are dominated by rocks made out of calcium carbonate, better known as limestone. These rocks react with the water very easily and get dissolved from it very easily. Because of the large scale dissolving, this type of topography has numerous specific features. Some of the most common features in the karst topography are the caves, sinkholes, caverns, funnel-shaped holes, underground rivers, underground lakes etc. All of them are very attractive and understandably cause a lot of interest, thus they are often tourist destinations, but more importantly of big scientific interest. The biggest problem with this topography is that it is generally not stable, and it is very common that the rocks can crumble, which makes them relatively dangerous if visited at certain periods of the year, especially when there is more precipitation.
