Einstein's stand against nuclear weapons places scientific knowledge before which ethical question?

Correct answer: Whether knowledge will be used for human protection or destruction

The governing concept is the ethics of scientific responsibility. Scientific knowledge is not automatically good or bad; its moral value depends greatly on the purposes and consequences of its use. Einstein’s concern about nuclear weapons highlights the danger that discoveries and advanced physics may be turned into instruments of mass destruction. It also raises the responsibility of scientists and governments to protect human life, pursue peace, and consider long-term consequences before applying knowledge. Option A is correct because it states this protection-versus-destruction dilemma directly. Options B, C, and D do not address the moral consequences of weapons or the responsibilities attached to science.
