The sentence highlights the consequences of insufficient climate finance for vulnerable nations. The structure "a cycle of ___ and ecological crisis" suggests that the blank must be a noun that pairs logically and grammatically with "ecological crisis" and fits the idea of being trapped in a repeated, worsening situation. The sentence warns that a lack of support could lead to worsening financial or structural challenges.
Option (a): This is an adjective, not a noun, so it does not fit grammatically. Also, being "independent" contradicts the idea of being "caught in a cycle," which implies reliance or entrapment. This option is incorrect.
Option (b): "Rejection" is a noun, but it doesn't logically pair with "ecological crisis" to form a meaningful or cohesive "cycle of rejection and ecological crisis." Rejection of what? The context doesn't support this term. This option is incorrect.
Option (c): "Dependency" is a noun and fits perfectly both grammatically and contextually. It refers to a situation where these nations become increasingly reliant on external aid or systems, especially in the absence of consistent climate financing. It pairs well with "ecological crisis" to describe a vicious cycle. This option is correct.
Option (d): "Chose" is the past tense of a verb, not a noun, so it cannot grammatically fill the blank. It also makes no contextual sense in the phrase "cycle of chose and ecological crisis." This option is incorrect.
Option (e): "Renew" is a verb, and cannot grammatically serve as a noun in this construction. A cycle of "renew" makes no meaningful sense in context. This option is incorrect.
Hence, option (c) is the answer.
