We are tasked with forming passwords using three components:

1. One non-zero digit
2. One vowel
3. One consonant

The password must start with a vowel and end with a consonant. Here's how we can break it down:

Non-zero digits: There are 9 possible non-zero digits (1, 2, 3, 4, 5, 6, 7, 8, 9). Vowels: There are 5 vowels in the English alphabet (A, E, I, O, U). Consonants: There are 21 consonants in the English alphabet.

The structure of the password is: The first character must be a vowel ($5$ options). The second character must be a non-zero digit ($9$ options). The third character must be a consonant ($21$ options).

Thus, the total number of passwords that can be generated is: Total number of passwords = $5 \times 9 \times 21 = 945$

Therefore, the correct answer is $945$.
