WHY DON’T ANY OF YOUR SOLUTIONS PROVIDE THE MEANS TO COPY – PASTE. THIS IS HIGHLY EXHAUSTING TO WRITE SO MANY THINGS. OTHER WEBSITES GIVE THE MEANS. YOU HAVE EXCELLENT ANSWERS BUT THEN MOST CUSTOMERS WON’T VISIT YOUR WEBSITE IF YOU DON’T PROVIDE COPY – PASTE OPTIONS. I KNOW YOU RESPECT YOUR PRIVACY AND DON’T ENCOURAGE PLAGIARISM, BUT THAT’S JUST IRONICAL BECAUSE YOUR LITERALLY PROVIDING ANSWERS ALREADY SO THAT’S LITERALLY THE 1ST STEP OF PLAGIARISM. THE 2ND STEP IS ALLOWING COPY – PASTE OPTIONS. THIS IS JUST A BUSINESS ADVICE I’M TELLING YOU… KINDLY PROVIDE ALL ANSWERS OF CLASS 10 IT CBSE SOLUTIONS IN COPY – PASTE FORM.
