Answer:
D
Step-by-step explanation:
The P/B ratio of 0.5 suggests that the market values Corporation A's book value at half its market price. This could indicate that the market has uncertainties or lack of confidence in the future profitability and growth prospects of Corporation A. Since the P/B ratio is not an indicator of future ROCE expectations, it is reasonable to assume that the market does not have a clear expectation regarding future ROCEs.
