‘S’ will be the first part of the given sequence as it states that the man waited for a long time to cross the road as mentioned in the opening sentence. ‘Q’ will come next as ‘fed up’ is used in the context of the ‘waited for long time’ mentioned in the very previous point. ‘R’ will come next as it states that what happened when the man was about to return. ‘P’ will pair with S6 as ‘driver got off’ is used in relation to ‘car stopped’. Hence,SQRP is the correct sequence. Thus, option (a) is correct.
