I think it is Option B. Some 3/2 splits available in the options. "In order to achieve" is preferable to "is required while growing"
So E and D are out.Also by POE
E is out since in order to is used twice and is clumsy
D usage of In order to,also while going business is not the proper form of usage.
C uses required and in order too together, it is not correct usage, both almost similar meaning"want or need"
Now A and B.
Who needs discipline?Answer to this and the option is clear.
Which is correct?
To check the patient's heartbeat, stethoscope is used.
OR
To check the patient's heartbeat, the doctor uses stethoscope.
I hope I am clear!
You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!
