Find All the Real Zeros of the Polynomial Function and Determine

Find all the real zeros of the polynomial function and determine the multiplicity of each zero and the number of turning points of the graph of the function.​ $h ( t ) = t ^ { 2 } - 14 t + 49$ ​

A) All Real Zeros: 0, $7$ ;Even multiplicity;number of turning points: 2
B) All Real Zeros: $7$ ;Even multiplicity;number of turning points: 1
C) All Real Zeros: 0, $49$ ;Odd multiplicity;number of turning points: 2
D) All Real Zeros: 0,1, $7$ ;Even multiplicity;number of turning points: 3
E) All Real Zeros: $7$ ;Odd multiplicity;number of turning points: 1
