  Option A is the most critical because wrong price data leads to bad financial decisions and heavy money losses. Conversely, Option D is less important because market price data is already public information—encrypting it doesn't matter if the numbers themselves are wrong.

  For market data, the most critical threats are integrity and accuracy.

• Chose B1

  A. The quality of the data is not monitored — correct The entire purpose of importing market price data is to use it for real financial decisions — pricing trades, valuing portfolios, reporting. If nobody checks whether that data is accurate/correct, the organization could be making major financial decisions on bad data without ever knowing it. This strikes at the core purpose of the process itself. Example: A trading firm imports a stock price feed, but a data provider glitch feeds in a wrong price for a stock. With no quality monitoring in place, that wrong price flows straight into trading decisions and financial reports — undetected.
