bearish flattening.
解释：
B is correct. A flight to quality is most often associated with bullish flattening, in which the yield curve flattens as long term rates fall by more than short-term rates.
During economic recession, bullish steepening happens because long-term bond yields decreases more than short-term bond yields resulting in a steepening yield curve.
