The crane supervisor shall, before starting to work a crane within station limit, obtain a written permission from. A. SM B. DME C. JE (CW) D. None of these

The correct answer is: A. SM

The SM (Safety Manager) is responsible for ensuring the safety of all personnel and equipment on the job site. They are also responsible for issuing permits for work that is considered to be high-risk. In this case, operating a crane within station limit is considered to be high-risk, so the crane supervisor must obtain a written permission from the SM before starting work.

The other options are incorrect because:

• The DME (District Maintenance Engineer) is responsible for the maintenance of equipment and facilities. They are not responsible for issuing permits for work.
• The JE (Construction Worker) is responsible for performing construction work. They are not responsible for issuing permits for work.
• None of these is the correct answer.

I hope this helps! Let me know if you have any other questions.
