B和C错哪里能说下吗

问题如下：

Ivan Paulinic, an analyst at a large wealth management firm, meets with his supervisor to discuss adding financial institution equity securities to client portfolios. Paulinic focuses on Vermillion Insurance (Vermillion), a property and casualty company, and Cobalt Life Insurance (Cobalt).

Paulinic’s analysis of the two insurance companies most likely indicates that:

选项：

Cobalt has more-predictable claims than Vermillion.

Cobalt has a higher capital requirement than Vermillion.

Vermillion’s calculated risk-based capital is more sensitive than Cobalt’s to interest rate risk.

解释：

A is correct.

Claims associated with life and health insurance companies (Cobalt) are more predicable than those for property and casualty insurance companies (Vermillion). Property and casualty insurers’ claims are more variable and “lumpier” because they arise from accidents and other unpredictable events, whereas life and health insurers’ claims are more predictable because they correlate closely with relatively stable actuarially based mortality rates when applied to large populations.
