Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Radio control
A Radio control allows selecting one option from a set, ideal for Approve/Reject decisions. Option D is correct because a Radio control presents mutually exclusive choices clearly on mobile. Option A is wrong because a Drop down requires an extra tap to expand, less intuitive for two options. Option B is wrong because a Checkbox is typically for binary yes/no but is not as clear for a single choice among two. Option C is wrong because a Text input requires typing, which is inefficient for a simple approval decision.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Drop down control
Why it's wrong here
A drop-down presents a list of choices but requires tapping to expand and select, adding interaction steps unsuited to quick mobile decisions. It is the right control when selecting one value from many predefined options, such as choosing a category or region, not for a two-outcome approve/reject action.
- ✗
Checkbox control
Why it's wrong here
A checkbox returns only a true/false Boolean, so it cannot capture two distinct named outcomes — approve or reject — as separate selectable values. It suits scenarios requiring a single binary toggle, such as confirming a terms acceptance, rather than recording which of two decisions a manager chose.
- ✗
Text input control
Why it's wrong here
A text input accepts free-form typed characters, so it cannot constrain the manager to the two defined outcomes of approve or reject, and risks inconsistent entries. It is correct when capturing unstructured data such as comments or a reference number, not a fixed decision.
- ✓
Radio control
Why this is correct
A radio control presents mutually exclusive options, letting managers select a single decision such as approve or reject. This satisfies the requirement to capture one definitive choice per request, preventing contradictory selections that checkboxes or text inputs would allow.
