This is the right way to capitalize the words in the sentence ""times change" is a song about the effects of the vietnam war."
Explanation:
Capitalization means the “first” letter of the word as capital and the rest of the word would be in lowercase. First letter of the first word of the sentence should be capital. Proper nouns, names, company names, historical periods must be in capital as it denotes something significant.
