The tense of the underlined segment is incorrect. Present perfect continuous tense should be used here. The present perfect continuous tense shows that something started in the past and is continuing at the present time. The present perfect continuous is formed using the construction has/have been + the present participle (root + -ing). |
“try to solve” should be replaced with “have been trying to solve”. Hence, option 1 is correct.
