Extraocular muscles are the first one to get involved in dermatomyositis.
The second best choice is lower limb muscles especially quadriceps
If the answer given is deltoid ( according to you ) then it is wrong !!!

Bohan and Peter proposed the criteria most widely cited for DM . These criteria include the typical rash of DM , findings at history and physical examination that reveal symmetric proximal muscular weakness, elevated serum muscle enzyme levels, electromyographic evidence of myopathic abnormalities, and characteristic findings at muscle biopsy.

lumbricals appear the most distant from the mid axis /trunk of the body.hence i think lumbricals is the answer

deltoid ,gluteal and quadriceps are relatively closer to mid axis than lumbricals.Symmetric proximal muscle weakness with insidious onset,Muscles usually painless with a common sparing of the occular muscles

the question should haver been least likely..than the answer should have been lumbricals.
