The keyword was polar other than that it would have been petritrichous.

Keyword was cluster because petritrichous is scattered not clustered.

Ha lophotrichous has two or more flagella at the pole of the cell it means it has cluster of polar flagella if he won't give cluster then it might be monotrichous because it has. Single polar flagella.

Lophotrichous means it has more flagella.

1. A single flagellum can extend from one end of the cell - if so, the bacterium is said to be monotrichous.

2. A single flagellum (or multiple flagella; see below) can extend from both ends of the cell - amphitrichous.

3. Several flagella (tuft) can extend from one end or both ends of the cell - lophotrichous.

4. Multiple flagella may be randomly distributed over the entire bacterial cell - peritrichous.

The severe flagella or tuft that extends only on one pole is called lophotrichous while the amphilophotricous has tuff flagella on both Poles.

I think the monotrichous is stroked with polar so it might mean one flagella term where single flagella is attacked to one pole.
