DS160 - Travel Info - Purpose of Trip to the U.S. - Specify category for parents travel

Hi,

I am filling DS160 for my parents visitor visa. After I select “TEMP. BUSINESS PLEASURE VISITOR (B)” in “Purpose of Trip to the U.S” whats the sub category to be selected in “Specify” option. I am confused which needs to be chosen among the 2 listed below:

“BUSINESS & TOURISM (TEMPORARY VISITOR) (B1/B2)” or
“TOURISM/MEDICAL TREATMENT (B2)”

My parents intend to visit USA while for tourism purpose only. There is neither goining to be any business related work nor medical treatment related work.

Please help which option is safe. Appreciate your inputs in advance.

Choose “TOURISM/MEDICAL TREATMENT (B2)”.
