Explanation:
The general outer electronic configuration of d-block elements is (n - 1)d1−10 ns1−2. Hence, d - block elements often have one or more unpaired d - electrons.
Due to presence of these unpaired electrons, transition elements show paramagnetism.
Therefore transition elements are often paramagnetic due to presence of one or more unpaired d electrons.
