Even if we combine the statements

- We have no dimensional constraint to draw to equilateral triangle of any specific size
-Radius of other two circles is unknown which may vary
- The point of tangencies is minimum one which doesn't restrict the movement of circles within the triangle and doesn't limit the size of other two circles

hence, Answer: Option E

The discrepancy in figure is as depicted in the attachment.
