Spouse works, filling box c step 2

I am married filled jointly and my husband works. On the step 2 (Multiple jobs or spouse works) of my W-4 I am not sure if I should select or not the box (c): "If there are only two jobs total, you may check this box. Do the same on Form W-4 for the other job. This option is accurate for jobs with similar pay; otherwise more tax than necessary may be withheld" because as my husband works, it would make sense to select this option. However, we do not have similar pay. Right now I don't have it selected, but I am not sure if this is correct. Thank you.
