Explanation:
Correct Answer is: I went there and sought a job.
Compound sentence-এ একের অধিক principal clause থাকে যাদেরকে co-ordinate clause বলা হয়।
অর্থাৎ Compound sentence এ দুই বা ততোধিক principal clause বা co-ordinate clause থাকে।
এছাড়া Compound sentence এ সাধারণত and, or, but, yet, so, therefore, otherwise, else, both — and , either — or , neither — nor, not only — but also ইত্যাদি co-ordinating conjunction দ্বারা দুইটি principal clause যুক্ত থাকে।
আর seek এর past/ past participle form হচ্ছে sought. প্রথম clause টি যেহেতু past tense এ আছে তাই দ্বিতীয় clause টিও past form এ হবে।
