$$H(m)=E(K, IV \oplus m) = C_1$$
|

$$H(m')=E(K, IV \oplus m') = C_2$$
|

And if there the hashing function was not collision resistant that would imply
|
||||
$$C_1=C_2\implies D(C_1)=D(C_2) \implies m=m'$$
|
||||
$$C_1=C_2\Rightarrow D(C_1)=D(C_2) \Rightarrow m=m'$$
|
||||
and since $m !=m'$ the hash function is collision resistant, for messages with 1 block.
