Solution
In active voice, the subject performs the action, in passive voice, the subject receives the action.
The given sentence is in passive voice, as it's seen that the subject "Concentration" receives the action, rather than performing it.
The verbs 'help', will help' and 'helps' are all active verbs, they are used when the subject is the doer of that action. Hence options A, B and C are not correct.
Option D, 'Helped' is correct as it's the only verb that forms a verb phrase in the passive voice.
['Is helped' refers to the simple present tense in passive form, as it follows the standard structure: is/are/am + past participle (helped)]
