Answer: E.
The idea
Convert every comparison into a single ordered chain. Once it is written out, the extremes read straight off.
Shortcut. The shortest is whoever is never said to be taller than anyone: E appears only as 'shorter than C'.
Common trap. "C" — the shortest person in the second clue, picked before the last clue puts E below C.
