Final answer:
According to the doctrine of predestination, it is true that a person's salvation is predetermined from birth, reflecting God's sovereign will and not related to individual actions or merits. The correct answer is A.
Step-by-step explanation:
The question pertains to the theological doctrine known as predestination, which is the belief that all events have been willed by God, especially with regard to the eternal fate of human souls. Specifically, the assertion is that, according to the doctrine of predestination, a person's salvation is predetermined from birth. The correct answer to this question is true.
In doctrines of predestination, such as those articulated by John Calvin, a key figure in the Protestant Reformation, it is indeed held that God predestines some people to salvation (the elect) and others to salvation (the reprobate), and this decision is not based on any actions or merits of the individual but solely on God's sovereign will. Hence the correct option is A.
