Select the alternative in which the specified components of the key figure (X) are found.

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

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

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

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

In fig. (X), one of the dots lies in the region common to the square and the triangle and another dot lies in the region common to the circle and the triangle. In each of the alternatives (1), (2) and (4), the region common to the square and the triangle lies within the circle. Therefore, in each of these figures, there is no region common to the square and the triangle only. Only the alternative (3) consists of a region common to the square and the triangle only and another region common to the circle and the triangle only. Hence, fig. (3) is the answer.
