The rate constant is numerically equal for three reactions of first, second and third order respectively. Which of the following is true?

Consider a reaction A →Products        ∴ r1=k[A]1 for1 st order           ......(i)              r2=k[A]2 for 2nd order            ....(ii)              r3=k[A]3 for 3rd order       .....(iii)∴   k is same in all the three cases.     If [A]=1,    r1=r2=r3If⁡[A]<1,    r1>r2>r3 If [A]>1,    r3>r2>r1
