BIntersection with a track where rail vehicles circulate.Correct
CUnattended level crossing.
Explanation
The upper vertical sign is a danger sign that indicates the proximity of an intersection with a track where rail vehicles circulate, such as trams. Upon seeing this sign, the driver must moderate their speed and redouble their attention. The remaining options refer to level crossings, whose danger signs feature different symbols: a fence or railing for a guarded level crossing (with gates or barriers) and a steam locomotive for an unguarded level crossing.
