The presence of basaltic clasts within the basal layers of the conglomerate indicates that the basalt must have been present before the conglomerate was formed. This implies that the basalt is older than the conglomerate. Additionally, the absence of any evidence of tectonic activity overturning the section suggests that the section has remained undisturbed, which supports the conclusion that the basalt is older than the conglomerate. Therefore, both statements B and C are correct.
