What must be true about the acceptance of an offer in Texas?

The acceptance of an offer in Texas contract law does indeed require the acceptance to mirror the original offer exactly, a principle that stems from the mirror image rule. This rule dictates that for an acceptance to be valid and create a binding contract, the terms of the acceptance must match the terms of the offer without any changes or conditions. If the acceptance strays from the original offer in any way—whether it's changing terms, adding conditions, or attempting to modify the agreement—it is considered a counteroffer, rather than an acceptance.

In Texas, like most jurisdictions, the clarity and mutual agreement in contract terms are vital for enforcing contracts. This is why mirroring the offer is essential; it ensures that both parties have a mutual understanding of their obligations and rights under the contract.

Regarding the other options, communications through any medium are allowed, but they do not have to "mirror" the offer in the same way that acceptance needs to for the contract to be enforceable. Conditional acceptances would not create an enforceable contract; instead, they would again be seen as counteroffers. While acceptance can be implied through performance in certain cases, this can only happen in specific contexts, such as in unilateral contracts, and does not apply to all situations of acceptance
