I wish I <i>____</i> on the time the film started before we came out.<br/><br/>a. would have checked<br/><br/>b. had checked<br/><br/>c. have checked.<br/><br/>As per my understanding it should be a...because sentence starts with as 'I wish' or the next best possible would be 'b' as second is in past tense<br/><br/>Please help thanks
