Correct answer: A — At least 90%

Explanation lettering: C = shown as B · E = shown as C · B = shown as E

The correct answer is **A: at least 90%**. UK quality-assurance guidance distinguishes between receptor types: conventional film images should achieve a minimum of 90% diagnostically acceptable ratings, while digital images have the higher target of 95%. The key discriminator in the stem is the reference to conventional film. Option D is therefore the most plausible distractor, but it is the digital-image target. Options B and C set thresholds below the recommended minimum. Option E is unnecessarily absolute: quality assurance recognises that occasional diagnostically unacceptable images can occur, provided they are identified, investigated and minimised.
