Choose from the options lettered A - E the one that most appropriately completes each sentence Bisi is a girl who can be relied_________

Analyze the question: The sentence is "Bisi is a girl who can be relied __." We need the preposition that correctly follows the verb "rely."

Explain the concept: The verb rely is followed by the preposition on or upon. It is a fixed verb-preposition pairing (a prepositional verb), so you cannot swap in other prepositions.

• rely on / rely upon ✔
• rely in, rely out, rely through ✘

Go through the options:

• A. in: "relied in" is wrong. There is no such pairing.
• B. onto: "onto" shows movement towards a surface (e.g., "jumped onto the table"). It is not used with rely. Note that "on to" and "onto" are different from "on" alone.
• C. out: "relied out" is wrong.
• D. through: "relied through" is wrong.
• E. upon: "relied upon" is correct. It is the formal equivalent of "relied on".

Complete sentence: "Bisi is a girl who can be relied upon."

Tip: Memorize common prepositional verbs in pairs: rely on/upon, depend on/upon, insist on, believe in, listen to, consist of. In NECO and JAMB Lexis and Structure questions, the answer is often simply the one preposition that naturally pairs with the verb. If "on" isn't offered, look for "upon".
