It seems that you have provided a mix of statements in Column A and options in Column B. Let's match the statements in Column A with the options in Column B based on the provided information:

4. Can be stopped by paper: This statement does not specify any specific type of radiation, so we cannot determine which option in Column B matches. More information is needed.

5. Can be stopped by aluminum: This statement suggests that the type of radiation can be stopped by aluminum. Given the options in Column B, the only option that matches is "b. Gamma."

6. Can be stopped by lead: This statement suggests that the type of radiation can be stopped by lead. Given the options in Column B, the only option that matches is "a. Beta."

So, based on the given information, we can match the statements as follows:

4. Can be stopped by paper: Cannot match (more information needed).
