The answer is A; because the rest are all accurate facts. 

A.  Working mothers are given 16 months maternity leave.

Explanation:

About 70% of the mother with children below 18 participate in the labor force and 75% are fully employed. And they primly earn 40% of the household as compared to that of 11% in the 1960's. The maternity leaves in the U.S states under the act of 1993, requires 12 weeks of unpaid maternity leave. The current laws are disproportionately for color and low-income women. That is below the 16-week minimum that is recommended by the WHO.
