(c) The requirement is to identify the bond provision
that is generally considered to be detrimental to the investor.
Answer (c) is correct because a callable bond is one that can be
redeemed at the option of the issuer. The investor has no choice
but to redeem the bond. Answer (a) is incorrect because a conversion
feature means the bond can be converted to common
stock at the option of the investor. This is a favorable provision
for the investor. Answer (b) is incorrect because redeemable
bonds are redeemable at the option of the investor. Answer (d)
is incorrect because bonds with serial maturity allow the investor
to select the desired maturity date.
