C) Transactions in a BMT bean do not propagate when the BMT bean calls a method on another bean.
D) A bean cannot use both CMT and BMT together.
E) BMT beans must not specify transaction attributes.
the answer is D E why A,C is incorrect,

Yes C Is incorrect as Transaction from BMT Bean can be propagated to CMT Bean.
