A deep depression over the Bay of Bengal is classified by the India Meteorological Department as a system that:

has intensified beyond a depression but is not yet necessarily a cyclonic storm

The report states that the system intensified into a deep depression and was expected to become a cyclonic storm. A reverses the sequence. C is a much stronger category. D is false because the system was over the Bay of Bengal. A is incorrect: is weaker than a low-pressure area does not satisfy the stated fact or is a different institution/concept. C is incorrect: is always a super cyclone does not satisfy the stated fact or is a different institution/concept. D is incorrect: forms only over land does not satisfy the stated fact or is a different institution/concept.
