The correct option is (c) IS
"No news is good news." — 'No news' is a singular subject (a phrase/concept), so it takes the singular verb 'is'.
This is a well-known English proverb. The subject 'No news' is treated as a singular noun phrase, so it requires the singular verb 'is'. 'Are' would be used for a plural subject. 'Has/Had' are incorrect as they change the meaning entirely. Examiners expect the student to identify subject-verb agreement and recognise the standard proverb form.
