final answer:
The corect option is c.The Roe v. Wade Supreme Court decision that legalized abortion in the United States took place in 1973, establishing the legality of abortions in the first trimester.
Step-by-step explanation:
The landmark case of Roe v. Wade legalizing abortion in the United States occurred in 1973. The Supreme Court's decision on Roe v. Wade was a significant historical event that established that abortions obtained during the first three months of pregnancy were legal.
This controversial decision in January 1973 not only invalidated a state law in Texas but also legalized abortion throughout the United States under certain circumstances, particularly during the first trimester, when abortions were deemed safer for women than childbirth itself. The case was a major victory for the feminist movement and changed the landscape of reproductive rights in America.
