These ultra-thin batteries would be composed of a ------- that reacts with the sodium and chloride ions in human tears thus generating the power needed for the contact lens. Which choice completes the text so that it conforms to the conventions of Standard English? glucose oxidase coating, eliminateglucose, oxidase coating eliminateglucose oxidase coating eliminateglucose, oxidase coating,eliminate

To complete the text so that it conforms to the conventions of Standard English, we need to choose the option that fits grammatically and contextually. The correct choice should be a single, coherent phrase that makes sense in the sentence.

Let's analyze the options:

1. glucose oxidase coating
2. eliminateglucose, oxidase coating
3. eliminateglucose oxidase coating
4. eliminateglucose, oxidase coating,eliminate

Option 1: "glucose oxidase coating" - This is a coherent phrase and fits well in the sentence. Option 2: "eliminateglucose, oxidase coating" - This option is not grammatically correct due to the lack of spaces and punctuation. Option 3: "eliminateglucose oxidase coating" - This option is also not grammatically correct due to the lack of spaces. Option 4: "eliminateglucose, oxidase coating,eliminate" - This option is not grammatically correct and includes unnecessary repetition.

Therefore, the correct choice is:

glucose oxidase coating

The completed sentence is:

These ultra-thin batteries would be composed of a glucose oxidase coating that reacts with the sodium and chloride ions in human tears thus generating the power needed for the contact lens.
