By looking for the right Idiom "worried about", it's easy to arrive at the OA (C) . But in C how does the tense work correctly because 'worried' is past tense and 'has formed' is present perfect. So I feel the ans must be A in order to match the tense

Please explain the usage of tenses in C

Hari, the tense shift that you indicate is justified by the logical meaning of this sentence. The current administration is worried about these two issues ("worried," though a past tense verb form, is used here with a present tense connotation that is highlighted by the term current). Thus, the current administration has formed a study group (the formation of the group began in the recent past, but the group continues to exist at the present moment).

I hope that makes sense!
