问题如下图：
选项：选项A会影响可转债债券属性的价值，选项C会影响可转债股票属性的价值，为什么不选B？
A. 
B. 
C. 
解释：
Whorton’s cret sprea. Whorton’s common stoprimovements. C is correct. The risk-return characteristiof a convertible bonpenon the market priof the issuer’s common sto(unrlying share price) relative to the bons conversion price. When the unrlying share priis well below the conversion price, the convertible bonexhibits mostly bonrisk-return characteristics. In this case, the priof the convertible bonis mainly affecteinterest rate movements anthe issuer’s cret sprea. In contrast, when the unrlying share priis above the conversion price, the convertible bonexhibits mostly storisk-return characteristics. In this case, the priof the convertible bonis mainly affectethe issuer’s common stoprimovements. The unrlying share pri($30) is lower ththe conversion priof Bon#9 ($50). Thus, Bon#9 exhibits mostly bonrisk-return characteristianis least affecteWhorton’s common stoprimovements. 老师请问，如果当W‘s common stoprice大于50的时候则convertible bon得更像股票，那么这题就应该选C了吧？
虽然现在股价显著小于转化价，但是ac都是会影响的因素啊，b为啥错了呢？没说股价不变了啊
为什么不选 b？？？
