Can someone help me on this question please super confusing Which claim from the speech best supports Warren’s argument that women face obstacles in addressing the wage gap?

“Today, more young women go to college than men, but unequal pay makes it harder for them to pay back student loans.”

“The effects of this discrimination are real, and they are long lasting.”

“Today, a woman can get fired for asking the guy across the hall how much money he makes.”

“Women today still earn only 77 cents for every dollar a man earns, and they're taking a hit in nearly every occupation.”
