Select the figure which satisfies the same conditions of placement of the dots as in Figure-X.

In fig. (X), one of the dots lies in the triangle alone, another dot lies in the region common to the square and the triangle only and the third dot lies in the region common to the circle and the square only. In each of the figures (1), (2) and (4), there is no region common to the square and the triangle only. Only fig. (3) consists of all the three types of regions.
