Two clauses are of equal rank or importance in a sentence when they are independent on their own and do not rely on each other for their full meaning, The conjunction used to combine these clauses is a coordinating conjunction. The are subdivided into various categories, depending on the nature of the two clauses. Here, the given clauses are independent on their own for their full meaning and are merely added to each other, hence a cumulative conjunction is to be used. 'Or' is used for 'alternative' clauses, where the sentence expresses a choice between the two clauses. Since the given statement does not express any choice, but is merely an addition, 'or' needs to be changed and option A is incorrect. 'And' is a cumulative conjunction that merely connects two sentences, and is appropriate for the given statement, hence option B is correct. 'Yet' is used for sentences that are adversative, i.e., those which express a contrast between two statements. Since the given statement does not express any contrast in meaning between the clauses, option C is incorrect. Similarly, 'but' is an adversative conjunction, hence option D is also incorrect.
