单项选择题 案例分析题

背景资料：

某工程项目模板支架在加载预压时垮塌，造成6人死亡、20人受伤的事故。事故调查组专家认为，事故的直接原因是：由于钢管立柱柱基不坚实，产生了一定的竖向和水平位移，桥梁施工支架支撑体系侧向约束薄弱，在堆载过程的外力作用下，由于支撑体系的局部变形引发支撑体系整体失稳破坏，造成支架垮塌。从现场观察和资料查阅情况看，支架体系在实施中存在以下主要问题：原设计单位要求的施工方案为满堂式支架，施工单位将满堂式支架的大部分改为贝雷支架，且未办理相关的更改和报批手续；对加载过程中引起的支架变形没有跟踪观测，不能适时了解支架加载过程中的变形情况，以便及时发现险情并采取有效措施确保安全。加载过程带有盲目性，施工中对支架进行加载时现场较乱，未能按一走的顺序加载。总而言之，这次事故是由于不完善的施工设计、不规范的施工作业，导致支架体系的失稳而垮塌。

该事故若构成犯罪，其罪名是（）。

A.渎职罪

B.重大责任事故罪

C.重大安全事故罪

D.重大劳动安全事故罪
