Which statement about the Residential Tenancies Act is inaccurate?

Inaccurate means not correct, so the statement that is not correct is that a tenant must submit post-dated cheques for rent payments. This is incorrect because the Residential Tenancies Act does not require tenants to use post-dated cheques for rent payments, they can use other forms of payment if agreed upon by both the landlord and tenant. The other statements are all accurate, with A regarding rent receipts, C regarding rent increase notice, D regarding dispute handling, and E regarding rent changes. Choice F is also correct as tenants do have rights to request repairs within a reasonable time.
