有另一说法

that..fields...and this interaction can bring

field 和interaction并列主词
            

虽然是说的通
            可是我觉得过于分裂

vote for A  一致性  that .......and that......

34cocorate

SSS ，同位语，
                can interfere  只有A合适

ijane

that the magnetic fields...and this interaction can bring on missed or irregular heartbeats...
就算是两个名词并列,一个是实义名词,一个是抽象名词,功能也不对称;然后,可以说 this interaction can bring on missed or irregular heartbeats,那也不能说the fields can bring啊!
所以,支持A
