In promastigote the position of kinetic apparatus is:

D) At the posterior end

Explanation:

The disease ORIENTAL SORE is caused by :

Cutaneous leishmaniasis, a relatively mild skin disease commonly known as oriental sore, is caused by Leishmania tropica in the Old World and Leishmania mexicana in the New World. It is the most common of the leishmaniases and represents 50 to 75% of all new cases. Unlike the amastigote of L. donovani, those of L. tropica and L. mexicana are found primarily in macrophages around cutaneous sores. Sandflies must feed at these sites in order to acquire the infective amastigotes.
