what was the approach of ida b. wells to segregated street-cars and white-owned stores?

1.wells started her own line of hair care products.

2.wells called for a boycott.

3.wells called for protest marches against segregation.

4.wells encouraged african americans to walk and start their own businesses.

Your answer will be 

4.Wells encouraged African Americans to walk and start their own businesses.

African Americans used their own transportations and those of their supporters that were willing to help them out.
They also went about and started their own businesses so that they didn't have to buy from white Segregationists that control the market

hope this helps
