Final answer:
Maryland was started as a safe place for Catholics but offered tolerance to all Christians through the Maryland Toleration Act of 1649.
Step-by-step explanation:
The colony that was started as a safe place for Catholics, but offered tolerance to all Christians, is Maryland (option a). The Maryland Toleration Act of 1649 guaranteed religious freedom to all Christians and established a liberal religious policy that was uncommon in the English colonies at the time. However, the law only applied to Christians, and anyone who denied the divine nature of Christ could be put to death.
