Step 1: Check subject consistency. The original sentence mixes "one" with "you," which is grammatically inconsistent.
Step 2: Review options.
- (a) mixes "one" with "you" → inconsistent.
- (b) keeps both parts consistent ("one … he") → grammatically correct.
- (c) mixes "you" with "one" → inconsistent.
- (d) mixes "one" with "you" → inconsistent.
Step 3: Final sentence.
The best version is option (b).
\[
\boxed{\text{When one reads … he finds …}}
\]
