The correct option is A was issued
Here, 'was issued' in simple past tense is correct because it
indicates an action that has already been completed. Here, the order 'was issued' (in the past) under Section 144.
'Were' is incorrect because the subject (order) is in singular form. So, verb used cannot be in plural form (were). It can be only in singular form (was).
'Had been issued' in past perfect continuous is incorrect
because it is used to indicate an action in the past that began before a
certain point in the past and continued up untill that time.
'Have been issued' in present perfect continuous tense is
incorrect because it is used to indicate an action that started at some point
in the past and may or may not be complete.
