The error is in part (A) of the sentence, which reads, "Although I am playing cricket for more than three years." The correct version should be, "Although I have been playing cricket for more than three years."

The reason for this correction is that the original sentence uses the present continuous tense, "am playing," which is not appropriate for expressing an action that has been ongoing for a specific period of time. The correct tense to use in this context is the present perfect continuous tense, as in the corrected sentence, "have been playing," to indicate that the action of playing cricket has been happening over the past three years.
