The answer is B
Please i need an explanation …why A wrong !!

B is better since the verb tenses agree.

But in A isnot (would) agree with( were) in the tense…!! So why we consider A wrong!!

Please…can anybody answer
my question… [-O<

Would is the past tense of will. Here you don’t need the past tense would. It’s better to use were as @MITer94 said.

“would” as it seems to be used here signals a repeated or habitual action. For example, it’s OK to write, “Every morning, I would see her waiting at the bus stop.” But it seems highly unlikely that Jamal told his story repeatedly. So the problem is mixing a verb that denotes a single event with a verb that denotes a repeated event.

The verbs in the correct answer all describe a single event.

(It is also possible that “would be pleased” is being used to signal the subjunctive, or counterfactual, mode, but that doesn’t work either, since the other verbs seem to indicate that the action did in fact occur.)
