To answer this question, you need to understand the commands used to save a dataset in view mode.
Let's go through each option to understand why it is correct or incorrect:
Option A) zf.zl - This option is incorrect because the command "zf.zl" is used to save a dataset in write mode, not in view mode.
Option B) repl - This option is incorrect because the command "repl" is used to replicate a dataset, not to save it in view mode.
Option C) repl.zf.zl - This option is correct. The command "repl.zf.zl" is used to save a dataset in view mode. The "repl" command is used to replicate the dataset, and the "zf.zl" command is used to save it in view mode.
Option D) replace - This option is incorrect because the command "replace" is used to replace values in a dataset, not to save it in view mode.
The correct answer is Option C) repl.zf.zl. This option is correct because it combines the "repl" command to replicate the dataset and the "zf.zl" command to save it in view mode.
