A、The man enjoyed the beauty of the evening sky from his plane. B、The man had a time bomb bidden in his suitcase. C、The ticking

After traveling in a crowded bus and waiting in the noisy airport building, I was glad to be sitting in the plane at last. In a few minutes now we would be asked to fasten our seat belts and to stop smoking, and then we would soon be up in the sky on our flight to Berlin.
    But I had been mistaken. Ten minutes later, instead of enjoying the beauty of the evening sky from high above the clouds, I was sitting in a smoke-filled room with an airline official and a police officer at my side. On the table in front of me was one of my suitcases.
    The officials were very polite. They asked me to show them my passport, my ticket, and my baggage check. Then I was requested to open the suitcase and to spread out its contents on the table.
    I did as I was told. The moment I placed a battery-powered alarm clock I bought for my father on the table, the two officials looked at each other and smiled. Hearing the clock ticking away merrily, I suddenly understood. Someone must have heard the ticking noise coming from my suitcase and thought there was a time bomb hidden in it.
