Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): α -halocarboxylic acid on reaction with dil. NH 3 gives good yield of α -amino carboxylic acid whereas the yield of amines is very low when prepared from alkyl halides. Reason (R): Amino acids exist in zwitter ion form in aqueous medium. In the light of the above statements, choose the correct answer from the options given below :

Both (A) and (R) are correct and (R) is the correct explanation of (A).
