Spot the error in the sentence: -

Although I am playing cricket for more than three years, I have not been able to score a century.

(A) Although I am playing cricket
(B) for more than three years
(C) I have not been
(D) able to
(E) score a century

Choose the correct answer from the options given below :

(A) only

The error is in the tense consistency. When expressing the duration of an action that started in the past and continues into the present, it's more appropriate to use the present perfect continuous tense.

The corrected sentence would be:

"Although I have been playing cricket for more than three years, I have not been able to score a century."

Now, the present perfect continuous tense "have been playing" is used to convey that the action of playing cricket started in the past and has continued up to the present. This is more grammatically accurate in this context.
