Let \mathbb{R}^3 denote the three-dimensional space. Take two points P=(1,2,3) and Q=(4,2,7). Let {\dist}(X, Y) denote the distance between two points X and Y in \mathbb{R}^3. Let S= \{X \in \mathbb{R}^3:({\dist}(X, P))^2-({\dist}(X, Q))^2=50\} and T= \{Y \in \mathbb{R}^3:({\dist}(Y, Q))^2-({\dist}(Y, P))^2=50\}. Then which of the following statements is (are) TRUE? [JEE Adv 2024 P1]

There is a triangle whose area is 1 and all of whose vertices are from S.

There are two distinct points L and M in T such that each point on the line segment L M is also in T.

There are infinitely many rectangles of perimeter 48 , two of whose vertices are from S and the other two vertices are from T.

There is a square of perimeter 48 , two of whose vertices are from S and the other two vertices are from T.
