Answer
(c) The debating teams were very happy as they had been declared joint champions..
This question is about the SEQUENCE OF TENSES. The main clause is in the simple past ("were very happy"), and the declaring happened BEFORE the happiness — so the subordinate clause must go one step further back, into the past perfect: "had been declared".
The rule to carry away: when the main verb is past, a subordinate verb describing an EARLIER event takes the past perfect.
Why the others fail: (a) mixes past with present perfect — "were... have been" does not agree. (b) shifts the whole sentence into the present, changing the meaning. (d) shifts it into the future, changing the meaning again.
