B. `"Incus"rarr"stapes"rarr"malleus"`
C. `"Stapes"rarr"incus"rarr"malleus"`
D. `"Malleus"rarr"stapes"rarr"incus"`

Answer

To determine the sequence of ear ossicles from outside to inside, we will follow these steps:

### Step 1: Identify the Ear Ossicles
The three ear ossicles are:
1. Malleus
2. Incus
3. Stapes

### Step 2: Understand Their Arrangement
The arrangement of these ossicles in the middle ear is crucial. The Malleus is the outermost ossicle, followed by the Incus, and then the Stapes, which is the innermost ossicle.

### Step 3: Confirm the Sequence
From the outside to the inside, the correct sequence of the ear ossicles is:
- Malleus (hammer)
- Incus (anvil)
- Stapes (stirrup)

### Step 4: Evaluate the Options
Now, let's evaluate the given options:
1. Malleus, Incus, Stapes - This is the correct sequence.
2. Incus, Stapes, Malleus - This is incorrect.
3. Stapes, Incus, Malleus - This is incorrect.
4. Malleus, Stapes, Incus - This is incorrect.

### Conclusion
The correct answer is the first option: Malleus, Incus, Stapes.
