Which of the following sentences is correct? Option 1: Though my grandfather is very old but he is very active. Option 2: My grandfather is not inactive for his old age. Option 3: My grandfather is without activities but his old age. Option 4: Although my grandfather is very old, he is very active.

Option 4 is correct because it uses 'Although' correctly without the redundant 'but' that makes Option 1 incorrect. Option 2 is awkwardly phrased and slightly unclear. Option 3 is grammatically incorrect and does not make logical sense. Option 4 correctly balances the sentence structure and clarity, making it the only grammatically correct choice.
