For a positive by charged particle moving in a x-y plane initially along the x-axis there is a sudden change in its path due to the presence of x-y plane and is found to be non-circular. Which one of the following combinations is possible?

`vecE` = 0; `vecB` = b`hati` + c`hatk`
`vecE` = a`hati`; `vecB` = c`hatk` + a`hati`
`vecE` = O`vecB` = C`hatj` C`hatj` + b`hatk`
`vecE` = a`hati`; `vecB` = c`hatk` + b`hatj`
