You can request option 3 for any offence and seek disclosure. Disclosure for this type of charge would consist of little more than the officer's notes. If you have no court room experience and the officer is reasonably competent, you'd probably have a hard time winning. Best to seek legal representation if you're adamant about fighting it. The other option is to request a first attendance meeting and see if the Crown will offer you a plea to a lesser charge.
If you entered on an amber light, then it's a strict liability offence, making it easier to dispute. That means if you showed due diligence (couldn't safely stop, didn't suddenly floor it to go through), you have a defence. If the officer charged you with a red light offence but you entered on the amber, that means the charge should be dropped since it's incorrect. Of course if the officer charged you with a red light offence, he probably believes you entered on the red. If his notes however say you entered on the amber light, the Crown should simply drop the charge.
Speeding up to go through the amber probably wasn't a good idea, and caught the officer's attention. Based on what you've said, the officer would have had pretty strong case against you for just the amber light charge. Remember, the goal is to stop, not to try and make it through. If you're accelerating, it makes it harder to argue you were unable to stop AND proceeding with caution.
