Concept:A conclusion necessarily follows only if it is directly and completely supported by the given statement without any assumption.
Explanation:The statement mentions both vehicle emissions and industrial emissions as contributors. Therefore, we cannot conclude that vehicle emissions are the primary cause. So conclusion I does not follow.
The statement clearly says consumers hesitate due to concerns about charging infrastructure and higher upfront costs. This directly shows practical barriers to electric vehicle adoption. So conclusion II follows.
The statement explicitly says industrial emissions also contribute and requires comprehensive policy reforms beyond the transportation sector. This supports the need for multi‑sectoral interventions. So conclusion III follows.
Thus only conclusions II and III necessarily follow from the statement.
Answer:Both II and III follow. Option C.
