Let us analyze and match each sentence from List-I with the most appropriate word from List-II based on definition and grammatical context:

1. Sentence (A): "She was able to give a ______ explanation in the court for her presence near the crime scene."
In a legal context, an explanation needs to be believable, plausible, or convincing. The word "credible" (III) means capable of being believed or worthy of trust. Thus, (A) matches with (III).

2. Sentence (B): "The Rockland Hospital _____ with AIIMS to conduct a free cancer screening camp."
This sentence describes two medical institutions working together to achieve a common goal. The word "collaborated" (I) means to work jointly on an activity or project. Thus, (B) matches with (I).

3. Sentence (C): "Though she has shown only 4% improvement in achieving her target yet her efforts are _____"
The sentence structure contrasts a small improvement (4%) with praise for the effort. The word "creditable" (IV) means deserving public acknowledgment and praise, even if not outstanding or fully successful. Thus, (C) matches with (IV).

4. Sentence (D): "The doctors give the prognosis by ______ their diagnosis with several tests."
Here, the sentence refers to backing up, validating, or confirming a diagnosis using evidence from medical tests. The word "corroborated" (II) means to confirm or give support to a statement, finding, or diagnosis. Thus, (D) matches with (II).
